[Bug c++/45606] [4.5/4.6 Regression] match a method prototyped a typedef alias with the original type (using stdlib)
--- Comment #4 from dodji at gcc dot gnu dot org 2010-09-19 20:33 --- I rewrote the handling of typedef comparison to put canonical type comparison back. I believe this approach is simpler and happens to fix this issue.

Fixes all regressions of C FE's testsuite
This update fixes all the regressions I have noticed in the test suite of the C
FE. I have done the testing and debugging with bootstrap disabled.
This patch merges Tom's initial patch and my additions and should apply to
recent trunk.
Next step is to bootstrap the C FE and see/fix the remaining bugs that I
encounter there.
Here is what the patch does at the moment:
$ cat test.c
1 #define OPERATE(OPRD1, OPRT, OPRD2) \
2 OPRD1 OPRT OPRD2;
3
4 #define SHIFTL(A,B) \
5OPERATE (A,,B)
6
7 #define MULT2(A) \
8SHIFTL (A,1)
9
10 void
11 g ()
12 {
13MULT2 (1.0);/* 1.0 1;*/
14 }
$ ./cc1 -quiet test.c
While expanding macro OPERATE at test.c:2:8
While expanding macro SHIFTL at test.c:5:14
While expanding macro MULT2 at test.c:8:3

Enough to pass bootstrap for C and C++. I haven't tried bootstrapping the other FEs yet. There are still some caveats: * I have added an -fdebug-cpp option that (very) verbosely clutters the output of -E. This is useful for me, for debugging purposes. I think the final patch should have this option removed. * There are still some regression tests that are failing because they need updating. * I still need to add an option to disable the macro token location tracking. * The patch still does not handle token pasting It's true that is still work in progress, but I'd appreciate comments especially if you notice that I am doing something wrong. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=7263

--- Comment #3 from dodji at gcc dot gnu dot org 2010-05-17 12:30 --- Created an attachment (id=20678) -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20678action=view) Candidate patch On Fri, May 14, 2010 at 07:25:18AM -, jakub at gcc dot gnu dot org wrote: That said, it would be good to find out why we don't warn in that case; for [M_CONST + 6] we do warn. I think we don't warn in that case because M_CONST in the expression M_CONST + 6, M_CONST is an rvalue use and we recognize it as such via default_conversion that should be called on the arguments of the + expression. We fail to recognize the use of [M_CONST], because M_CONST gets folded into it's value without us marking that folding as an rvalue use. I am thus testing the attached patch. The reason why the patch seems convoluted is that I don't want to mark a dependant value as a rvalue use. I believe only full instantiations should be marked. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44108

[Bug debug/7580] incorrect/unfortunate DWARF-2 info for static const int class members
--- Comment #7 from dodji at gcc dot gnu dot org 2010-03-18 12:50 ---
Things have changed quite a bit in GCC 4.5 (trunk).
Now for the code:
class C
{
static const int foo;
};
int
main()
{
return 0;
}
GCC 4.5 will not generate any debug info for the class C at all, because it's
not used. The compiler does that to minimize the size of debug info.
Now if we write:
class C
{
static const int foo;
};
int
main()
{
C c;
return 0;
}
GCC generates debug info for C, and properly generates a DW_TAG_member for foo.
Note how we instantiate C in main, but don't reference C::foo in any way.
Here is a relevant DWARF portion of the assembly we get for this:
.uleb128 0x2# (DIE (0x2d) DW_TAG_class_type)
.ascii C\0# DW_AT_name
.byte 0x1 # DW_AT_byte_size
.byte 0x1 # DW_AT_decl_file (../../prtests/test.cc)
.byte 0x2 # DW_AT_decl_line
.long 0x49# DW_AT_sibling
.uleb128 0x3# (DIE (0x37) DW_TAG_member)
.ascii foo\0 # DW_AT_name
.byte 0x1 # DW_AT_decl_file (../../prtests/test.cc)
.byte 0x4 # DW_AT_decl_line
.long .LASF3 # DW_AT_MIPS_linkage_name: _ZN1C3fooE
.long 0x49# DW_AT_type
.byte 0x1 # DW_AT_external
.byte 0x1 # DW_AT_declaration
.byte 0x0 # end of children of DIE 0x2d
So I think we can close this bug now.

--- Comment #5 from dodji at gcc dot gnu dot org 2010-03-18 14:38 --- (In reply to comment #4) As we discussed on IRC, it seems we'd need a way to express that we'd want the debugger to create a temporary, initialize it and later destroy it. DWARF can't express as of now. So we'll probably need some kind of extension. I am not sure exactly what extension yet though.

With 4.5 I get this: 0b: Abbrev Number: 1 (DW_TAG_compile_unit) c DW_AT_producer: (indirect string, offset: 0x62): GNU C++ 4.5.0 20100301 (experimental) 10 DW_AT_language: 4(C++) 11 DW_AT_name: (indirect string, offset: 0x0): class.c 15 DW_AT_comp_dir: (indirect string, offset: 0x19): /home/dodji/devel/git/gcc-branches.git/gcc-PR37982.git/prtests 19 DW_AT_low_pc : 0x4004b4 21 DW_AT_high_pc : 0x4004c0 29 DW_AT_stmt_list : 0x0 12d: Abbrev Number: 2 (DW_TAG_structure_type) 2e DW_AT_name: A 30 DW_AT_byte_size : 1 31 DW_AT_decl_file : 2 32 DW_AT_decl_line : 2 33 DW_AT_sibling : 0x49 237: Abbrev Number: 3 (DW_TAG_member) 38 DW_AT_name: (indirect string, offset: 0x58): elsewhere 3c DW_AT_decl_file : 2 3d DW_AT_decl_line : 3 3e DW_AT_MIPS_linkage_name: (indirect string, offset: 0x8): _ZN1A9elsewhereE 42 DW_AT_type: 0x49 46 DW_AT_external: 1 47 DW_AT_declaration : 1 [...] 0a0: Abbrev Number: 1 (DW_TAG_compile_unit) a1 DW_AT_producer: (indirect string, offset: 0x62): GNU C++ 4.5.0 20100301 (experimental) a5 DW_AT_language: 4(C++) a6 DW_AT_name: (indirect string, offset: 0x8d): class2.c aa DW_AT_comp_dir: (indirect string, offset: 0x19): /home/dodji/devel/git/gcc-branches.git/gcc-PR37982.git/prtests ae DW_AT_low_pc : 0x4004c0 b6 DW_AT_high_pc : 0x4004c0 be DW_AT_stmt_list : 0x46 1c2: Abbrev Number: 2 (DW_TAG_structure_type) c3 DW_AT_name: A c5 DW_AT_byte_size : 1 c6 DW_AT_decl_file : 1 c7 DW_AT_decl_line : 2 c8 DW_AT_sibling : 0xde 2cc: Abbrev Number: 3 (DW_TAG_member) cd DW_AT_name: (indirect string, offset: 0x58): elsewhere d1 DW_AT_decl_file : 1 d2 DW_AT_decl_line : 3 d3 DW_AT_MIPS_linkage_name: (indirect string, offset: 0x8): _ZN1A9elsewhereE d7 DW_AT_type: 0xde db DW_AT_external: 1 dc DW_AT_declaration : 1 [...] 1ea: Abbrev Number: 6 (DW_TAG_variable) eb DW_AT_specification: 0xcc ef DW_AT_decl_file : 2 f0 DW_AT_decl_line : 2 f1 DW_AT_location: 9 byte block: 3 ac 5 40 0 0 0 0 0 (DW_OP_addr: 4005ac) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37982

[Bug debug/42959] g++ does not emit DW_AT_default_value
--- Comment #1 from dodji at gcc dot gnu dot org 2010-03-11 16:17 --- Created an attachment (id=20085) -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20085action=view) Draft patch Please find below a copy/paste of the introductory comment of the attached patch. Basically the value of DW_AT_default_value -- as explained by the DWARF4 draft specification -- is either a constant if the default argument of the function is a constant, or a reference to a DIE if the value of the default argument is a language construct like a variable. I believe there are cases however where it's hard (impossible yet?) to represent the value of DW_AT_default_value. For instance, when the default argument of a function F is an arbitrary expression that yields temporaries. In that case, the default argument expression must be evaluated in the context of the caller of F. Just taking in account the default argument expression in the context of the F declaration is not enough. I am not sure we can represent that in DWARF today, can we? So this patch is limited to the simple cases were the default argument is either a constant or a variable that does not involve any temporary. When a default argument expression involves some temporaries, no debug info is generated for it. For a class, it appears that we were calling finish_struct right before parsing default arguments of the member functions. finish_struct does the layout of the class. So we do the layout of the class before parsing the defaut arguments because they can refer to parts of the struct that need to be constructed before. The problem is finish_struct also generates debug info for the class. That means, when we generate debug info for the struct, we don't have any information ready about the default arguments. The patch allows finish_struct to not emit debug info systematically. We can then keep calling finish_struct early and emit debug info only after we parsed the default arguments. We do something similar at class template instantiation time. We emit debug info only after the template arguments are substituted into the default arguments expressions. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42959
