[Bug fortran/32555] [4.3 Regression] Miscompilation of NIST testsuite
--- Comment #2 from burnus at gcc dot gnu dot org 2007-06-30 06:49 --- FM403.f, FM900.f, and FM903.f fail to compile. I have confirmed this regression is caused by. 2050 FORMAT(2PF8.3,-2PE9.4,F9.4,0PF9.4,9X,-2PE9.4,F9.4) 1 Error: Unexpected element in format string at (1) The problem is that the big case block in check_format was checking only for FMT_POSINT and (for k P, Fortran2003: R1011/R1012) for FMT_SIGNED_INT; however, format_lex can return another state: FMT_ZERO. But due to a bug it was never returned. As P seems to be the only element where zero is allowed, I did the patch as follows. I'm not sure I can submit the patch in the coming days; feel free to submit it.

[Bug bootstrap/32556] New: The libgcc configuration file doesn't swap CPP when it swaps CC - use of normal value breaks make
According to gcc-4_3-trunk/libgcc/configure's help we can set some environment vars before we compile gcc. Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -Llib dir if you have libraries in a nonstandard directory lib dir CPPFLAGSC/C++ preprocessor flags, e.g. -Iinclude dir if you have headers in a nonstandard directory include dir CPP C preprocessor Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations. For what I am doing I have set CC and CPP. In the text that follows I have deleted portions for brevity and then substituted ... where I am reasonably sure I am not cutting out something of use. Here is a few lines from the config.log files: With CPP set in the environment - i686-pc-linux-gnu/libgcc/config.log: configure:3015: checking how to run the C preprocessor configure:3133: result: gcc -E configure:3157: gcc -E conftest.c configure:3163: $? = 0 configure:3195: gcc -E conftest.c Without CPP set in the environment - i686-pc-linux-gnu/libgcc/config.log: configure:3015: checking how to run the C preprocessor configure:3050: /opt/gcc-4_3-build-6/./gcc/xgcc -B/opt/gcc-4_3-build-6/./gcc/ ... configure:3056: $? = 0 configure:3088: /opt/gcc-4_3-build-6/./gcc/xgcc -B/opt/gcc-4_3-build-6/./gcc/ ... conftest.c:9:28: error: ac_nonexistent.h: No such file or directory configure:3094: $? = 1 configure: failed program was: | /* confdefs.h. */ | | #define PACKAGE_NAME GNU C Runtime Library | #define PACKAGE_TARNAME libgcc | #define PACKAGE_VERSION 1.0 | #define PACKAGE_STRING GNU C Runtime Library 1.0 | #define PACKAGE_BUGREPORT | /* end confdefs.h. */ | #include ac_nonexistent.h configure:3133: result: /opt/gcc-4_3-build-6/./gcc/xgcc -B/opt/gcc-4_3-build-6/./gcc/ ... configure:3157: /opt/gcc-4_3-build-6/./gcc/xgcc -B/opt/gcc-4_3-build-6/./gcc/ ... configure:3163: $? = 0 configure:3195: /opt/gcc-4_3-build-6/./gcc/xgcc -B/opt/gcc-4_3-build-6/./gcc/ ... The configure script is combining how to run the C preprocessor with the CPPFLAGS or alternately, once it figures out how to run the C preprocessor then it does not add the (internal) CPPFLAGS (the -B commands) so it can use the -B stuff with the chosen CPP. It is not using _my_ CPPFLAGS either but I can get over that. If your thinking that this has something to do with cross-targets then I would mention that I also set CC and it is using 'gcc-4_3-build-6/gcc/xgcc' for libgcc (which it likely should) - so when I have set CPP why doesn't it use 'the xcpp' (gcc-4_3-build-6/gcc/cpp) - with or without -B ... -isystem ... ? When the build thinks it is correct to switch from _my_ choice of CC to the recently built gcc (xgcc) why doesn't it switch from _my_ choice of CPP to the recently built xccp (simply called gcc/cpp) ? It follows that when one switches the other should at the same time. Here is some screen output that I logged: With CPP set in the environment: Line: 2077 /opt/gcc-4_3-build-5/make_26c_log.txt Configuring stage 1 in i686-pc-linux-gnu/libgcc checking whether we are using the GNU C compiler... yes checking whether /opt/gcc-4_3-build-5/./gcc/xgcc -B/opt/gcc-4_3-build-5/./gcc/ ... checking for /opt/gcc-4_3-build-5/./gcc/xgcc -B/opt/gcc-4_3-build-5/./gcc/ ... checking how to run the C preprocessor... gcc -E checking whether decimal floating point is supported... yes Without CPP set in the environment: Line: 2883 /opt/gcc-4_3-build-6/make_27_log.txt Configuring stage 1 in i686-pc-linux-gnu/libgcc checking whether we are using the GNU C compiler... yes checking whether /opt/gcc-4_3-build-6/./gcc/xgcc -B/opt/gcc-4_3-build-6/./gcc/ ... checking for /opt/gcc-4_3-build-6/./gcc/xgcc -B/opt/gcc-4_3-build-6/./gcc/ ... checking how to run the C preprocessor... /opt/gcc-4_3-build-6/./gcc/xgcc -B ... checking whether decimal floating point is supported... yes Notice on the checking how to run the C preprocessor line that if CPP is set then that is all you get, no -B - that could be OK if you wanted to use your own choice of cpp throughout. Why does the script think we can run gcc/xgcc and not gcc/cpp (is it worried about a cross). For _my_ purposes I will need to fix this. I don't know enough about all the cross environments that others use to suggest how the trunk needs to be changed in a compatable manner. Whatever the reasoning for keeping it we end up in trouble. To top it off, further on in the build the makefiles and configure scripts get confused and keep adding the library directory to the GCC command until the line gets too long and blows up collect2. It gets to here before it gets confused - first it is using xgcc, then it decides to use gcc with a short command line to link ./libgcc_s.so.1.tmp. Next it keeps adding more and more iterations of command fragments ... gcc -D_GNUCC -o ./libgcc_s.so.1.tmp

[Bug rtl-optimization/32475] [4.3 Regression] function with asm() does not setup stack frame
--- Comment #12 from richard at codesourcery dot com 2007-06-30 12:58 --- Subject: Re: [4.3 Regression] function with asm() does not setup stack frame richard at codesourcery dot com [EMAIL PROTECTED] writes: zadeck at naturalbridge dot com [EMAIL PROTECTED] writes: Could you check to see if this bug is collateral damage from your latest fix to deletable_insn_p. It's appearance has been tied to that function in the past. _My_ latest fix to deletable_insn_p? ;) All I did was rephrase your patch in terms of deletable_insn_p_1. Sorry, I shouldn't have said that. Kenny's original patch was basically an implementation of something I'd suggested on IRC, so the ultimate blame does lie with me. I think the upshot is still the same: I don't really have time to work on this, and given that what I suggested was either wrong, or exposed some other latent problem, I think reverting the patch is the correct thing to do under the circumstances. I suggest that someone else looks at the problem that the patch was trying to solve (which AIUI was a pessimisation rather than a wrong-code bug).

[Bug c/32564] New: [libcpp] ICE in print_location() when stat() in remove_duplicates() fails
I had gcc 4.1.1 configured in such a way that when the resulting cc1 got invoked, the stat() call in remove_duplicates() failed with an errno different than ENOENT (calling chain at that moment was: remove_duplications() - merge_include_chains() - register_include_chains() - c_common_post_options() - toplev_main()). This results in calling cpp_errno() - cpp_error() - _cpp_begin_message() and finally print_location() which ICEs because map variable was NULL. The reason is that print_location()'s 'line' parameter was bogus (random value). That value was determined in cpp_error() as src_loc : src_loc = pfile-cur_token[-1].src_loc;. The pfile-cur_token[-1] struct contains bogus values at this point. In attached patch I address this ICE twofold: 1) Make src_loc 0 in cpp_error() when no tokens have been read yet. 2) Check for NULL result of linemap_lookup(). -- Summary: [libcpp] ICE in print_location() when stat() in remove_duplicates() fails Product: gcc Version: 4.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: John dot Tytgat at aaug dot net http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32564

[Bug c++/32549] Wrong template instance resolution among multiple object files.
--- Comment #3 from opichals at seznam dot cz 2007-06-30 15:05 --- I am not sure about the standard wording. But logically typedefs local to a .cpp file should stay local to that file. They in fact are. However the template instances are not. If it should not be that way then the compiler should complain about such conflicts in some way not to get the two confused at runtime. Especially in huge application merges this is very critical. note: I am sorry, will be out of reach for the next few weeks to discuss in detail. I would appreciate any pointers or more detailed explanations you could provide. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32549

--- Comment #23 from ian at airs dot com 2007-06-30 17:57 --- The patch in comment #19 of PR 32437 looks clearly correct. That patch should not be reverted, at least not by itself. I'm not clear on whether that was the patch that was reverted, but, if it was, I don't think it should have been. We are not in a time critical situation here. Let's take the time to figure out the right fix even if Richard doesn't have time to work on it. This is DCE, not DSE. In DSE we can not eliminate frame related instructions, because the stores into the frame are used by code which dataflow doesn't see: the exception unwinder. That does not apply to DCE. In DCE, we should be able to eliminate changes to the stack pointer when the stack pointer is not used, even though those changes are frame related. So I think this patch should be unreverted, and I don't think you should add a test for frame relatedness. Then we should fix PR 32475.

--- Comment #13 from ian at airs dot com 2007-06-30 18:08 --- The problem here is that although the stack pointer is not used in the function, adjusting it does reserve space on the stack for the local variables which are used.

The problem here is that although the stack pointer is not used in the
function, adjusting it does reserve space on the stack for the local variables
which are used. The local variables are accessed via the frame pointer with a
negative offset. Deleting the adjustment of the stack pointer is causing that
the reference to be implicitly invalid. This test case makes the problem

doesn't know about. If the asm weren't there, though, there would still be a

corrupt the value of the local variables.
One possible approach to this is that DF should note that any reference to a
local variable via the frame pointer is implicitly a use of the stack
pointer.
Note that this doesn't necessarily mean a negative offset from the frame
pointer, although it does in this case. On processors like the Thumb even
local variables are accessed as positive offsets from the frame pointer, and
parameters are accessed by larger positive offsets. We also need to consider
whether any asm statement is a use of the stack pointer. It may be that DF
should treat an asm statement however it treats a function call with regard to
uses of the stack pointer. A non-volatile asm would be a const call, and a
volatile asm would be an ordinary call. I'm not completely sure about that,
but it seems worth considering.
A simpler approach would be for DCE to simply not remove adjustments to the
stack pointer. I believe this would have to be done whether the adjustment
was
frame related or not. I think the fact that the instruction is frame related
is probably a red herring here.
it is interesting to read the comments as a historical record to what we
do.
Looking at it from the point of view that we should treat asms more like
function calls, there is a disturbing comment in the code that scans the
asm inputs:
case ASM_INPUT:
{
/* Traditional and volatile asm instructions must be
considered to use and clobber all hard registers, all
pseudo-registers and all of memory. So must TRAP_IF and
UNSPEC_VOLATILE operations.
Consider for instance a volatile asm that changes the fpu
rounding mode. An insn should not be moved across this
even if it only uses pseudo-regs because it might give an
incorrectly rounded result.
However, flow.c's liveness computation did *not* do this,
giving the reasoning as ?!? Unfortunately, marking all
hard registers as live causes massive problems for the
register allocator and marking all pseudos as live creates
mountains of uninitialized variable warnings.
In order to maintain the status quo with regard to liveness
and uses, we do what flow.c did and just mark any regs we
can find in ASM_OPERANDS as used. In global asm insns are
scanned and regs_asm_clobbered is filled out.
For all ASM_OPERANDS, we must traverse the vector of input
operands. We can not just fall through here since then we
would be confused by the ASM_INPUT rtx inside ASM_OPERANDS,
which do not indicate traditional asms unlike their normal
usage. */
if (code == ASM_OPERANDS)
{
int j;
for (j = 0; j ASM_OPERANDS_INPUT_LENGTH (x); j++)
df_uses_record (collection_rec, ASM_OPERANDS_INPUT (x, j),
DF_REF_REG_USE, bb, insn, flags);
return;
}
break;
}
Asside from the fallout in the register allocator or uninitialized
warnings, there really is not problem adding the stack_pointer. Flow
could get away with it because it could assume that the rest of the
optimizations were stupid or had been neutered. I do not think that is
the way to go. We add the stack pointer not matter if the function call
is a const call or not. Note that const calls do generally read the stack.
Adding the stack pointer for asms is certainly the easiest thing to do.
If you think that we want to view mem refs off the frame pointer as if
they also touch the stack pointer, we can do that, but i would ask the
question as to why just in dce?

[Bug rtl-optimization/32475] [4.3 Regression] function with asm() does not setup stack frame
--- Comment #15 from iant at google dot com 2007-07-01 01:58 --- Subject: Re: [4.3 Regression] function with asm() does not setup stack frame Adding the stack pointer for asms is certainly the easiest thing to do. I don't know if that is enough. Maybe it is, maybe it isn't. You can't delete the subtraction of the stack pointer if there is any use of any local variable on the frame in any way. If an interrupt occurs, and the stack pointer has not been decremented to be below the local variables, then the local variables will be corrupted by the interrupt handler. If you think that we want to view mem refs off the frame pointer as if they also touch the stack pointer, we can do that, but i would ask the question as to why just in dce? I meant it should be done when doing dataflow scanning, not in DCE. I agree there is nothing special about DCE here. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32475
