Notice environment variable ADA_INCLUDES sent to Makfile in subdirectory, for native building, it is assigned to the ada include directory of source files, but for cross building it is assigned to the ada include directory of build toolchain. So for cross building, if the version of the source is different from the version of the toolchain, there may be some conflicts, such as constants declaration changes like SPARK--SPARK_05. Therefore, for cross building new toolchain, it is better to build a piece of native toolchain of the target version(upgrade or download) first, then using the new native toolchain of the same version to build the target cross toolchain. This will avoid the potential conflicts.

So would it work (and I realize this is a horrid hack) to have a way for the
backend to set the pic-pseudo as live at the key points during IRA? It'll
be overly conservative, but it may still be better than going back to a
fixed PIC register. If we had the conservative live information during IRA,
presumably it would flow through to LRA and avoid this problem?
I believe it will disable the optimization completely too. It is up to
Intel guys to decide how to disable the optimization *temporarily* with
minimal efforts most probably only for 2 weeks.
Following patch mitigates bootstrap problems:

The above patch solves all but corner problems, but generates non-optimal push
sequences for constants when general registers are available.
So, we can refer to the above hacky patch to fix current bootstrap problems.
This way it is possible to survive a couple of weeks, until the real fix is
available.

Francois, the bug is in _Reuse_or_alloc_node::_M_extract which returns a node
that has a child. When we reuse the node the child is lost.
The LHS of the assignment looks like this:
(gdb) p this-_M_impl._M_header
$1 = {_M_color = std::_S_red, _M_parent = 0x605010, _M_left = 0x605040,
_M_right = 0x605010}
(gdb) p *$1._M_left
$2 = {_M_color = std::_S_red, _M_parent = 0x605010, _M_left = 0x0, _M_right =
0x0}
(gdb) p *$1._M_right
$3 = {_M_color = std::_S_black, _M_parent = 0x7fffd668, _M_left = 0x605040,
_M_right = 0x0}
When that gets handed to the _Reuse_or_alloc_node
this-_M_impl._M_header._M_right-_M_parent gets set to null, so when
_M_extract returns 0x605010 it thinks it has no more nodes to reuse.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63573 --- Comment #6 from Jan Hubicka hubicka at gcc dot gnu.org --- OK, so the problem is the following. There is a parameter that is passed by reference. Because it is a single scalar (packed in structure) it gets promoted to register by function.c as an optimization. This however is not welcome by the tail call expansion code that needs to use original memory location to pass the parameter further. The original memory location is still linked by DECL_INCOMING_RTL that is readily available: Index: expr.c === --- expr.c (revision 216942) +++ expr.c (working copy) @@ -7660,6 +7660,13 @@ expand_expr_addr_expr_1 (tree exp, rtx t modifier == EXPAND_INITIALIZER ?

I am bit concerned about its safety however: DECL_RTL and DECL_INCOMING_RTL may not be kept in sync in real function (not thunk) and at this point we do not have any way to assert that we are not expanding thunk. However I think this is only place I can think of where TREE_ADDRESSABLE flag is validly set on value that is not in memory. Perhaps we could replace DECL_RTL by DECL_INCOMMING_RTL instead in calls.c at the place we mark it addressable to make IL more consistent?

Note that strictly speaking you should always use a stable release as your bootstrap compiler, and not a snapshot, precisely to avoid this kind of subtle temporary issues (which are very rare, but may occur).

[Bug c++/63692] Temporary object stack space is not re-used

We are affected by this in the debug builds which are built without any optimizations. Reviewing -O2 options I didn't find an option, which enables or disables reuse of temp object space. Is there one? P.S. On the other hand this is not an issue with POD types.
[Bug libgomp/63700] New: Is is impossible to set the OpenMP stack size from inside a program
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63700 Bug ID: 63700 Summary: Is is impossible to set the OpenMP stack size from inside a program Product: gcc Version: 4.9.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgomp Assignee: unassigned at gcc dot gnu.org Reporter: walter.zimmer at dlr dot de CC: jakub at gcc dot gnu.org We have a binary which uses a lot of stack due to external libray we have no control over. Single threaded, this is no problem, setrlimit() works fine. But for OpenMP, setting OMP_STACKSIZE seems to be the only option so set the stack size for OpenMP threads. Unfortunately, it can't be set from within the program, as the libgomp code is always executed before the main program code. We also tried __attribute__ ((constructor)) and section(.init), but for shared links, the libgomp code is always called before we can set rlimit or OMP_STACKSIZE (nice to see with OMP_DISPLAY_ENV). We really want to avoid having external dependencies, so we try to avoid having to set external environment variables. Having a small routine which sets the OpenMP internal stack size before the first threads are created would solve this problem. Such a routine is not specified in the standard, but it might be implemented as a gomp routine to account for that. Or did I miss something? Is this behaviour maybe intentional? What would be the best solution to set the OpenMP stack size inside a program?

[Bug target/61915] [AArch64] High amounts of GP to FP register moves using LRA on AArch64 - Improve Generic register_move_cost and memory_move_cost
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61915 --- Comment #20 from Evandro e.menezes at samsung dot com --- (In reply to Ramana Radhakrishnan from comment #19) To my mind it seems like 407 fmoves is just a bit too berserk and regardless of how efficient your core is, there is no point in having so many moves back and forth. It seems that the only LRA parameter exposed is lra-max-considered-reload-pseudos. It defaults to 500 and decreasing it, results in more FMOVs; increasing it, in less. It doesn't have any effect over 1000. At 1000, the number of FMOVs decreases by 5% in some cases.

[Bug c/59708] clang-compatible checked arithmetic builtins
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59708
--- Comment #11 from Jakub Jelinek jakub at gcc dot gnu.org ---
Created attachment 33855
-- https://gcc.gnu.org/bugzilla/attachment.cgi?id=33855action=edit
gcc5-pr59708-wip1.patch
WIP untested patch, which implements so far the clang compatible builtins (with
the exception of __builtin_umul*_overflow, that needs extra work) and has a
start of implementation for the Joseph's idea of type-generic builtins
(__builtin_{add,sub,mul}_overflow), which perform infinite precision signed
+/-/*, store some low bits into the memory pointed by the third argument and
return true iff the infinite precision signed result is equal to the stored
value.
Internally, where needed this is implemented as internal calls returning two
values as a _Complex int, which turned out to be easiest and generates very
good code during expansion.
I'll work on BUILTIN_UMUL*_OVERFLOW next and when that is done, continue
hacking on the type-generic stuff (so far it handles just the case where it is
easy to prove the operation never overflows, or where it can be handled like
the clang-compatible builtins (extended for other integral types like
char/short/__int128).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58938 frankhb1989 at gmail dot com changed: What|Removed |Added CC||frankhb1989 at gmail dot com --- Comment #11 from frankhb1989 at gmail dot com --- I'd like to say it should be a bug, if I did not get it wrong. Even for a freestanding implementation, ISO C++11 explicitly specified exception as one of required header in table 16, and it should meet the same requirements as for a hosted implementation. Missing exception propagation is definitely not conforming, whether it can actually be implemented or not. Moreover, the standard doesn't specify anything about atomic operations on exception propagation, though it does requires that there should be no data race during some operations. Atomic operations here seem to be purely implementation details. Can it be implemented with something like __shared_ptr's lock policy? This issue also has effect on nested exceptions. Anyway, I feel something indeed wrong when I have to miss std::nested_exception for this reason on a platform which has even no multithreading support at all (as allowed by C++11). Sigh. BTW, libstdc++ manual Table 1.2 just tell me 'Y' for 18.8.5 and 18.8.6. Found no other notes about this issue. So at least it can be a defect of documentation.

[Bug target/63691] GCC 4.9.x fails to build GLIBC 2.20 on HPPA
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63691 --- Comment #8 from Aaro Koskinen aaro.koskinen at iki dot fi --- (In reply to dave.anglin from comment #7) On 10/31/2014 2:39 PM, aaro.koskinen at iki dot fi wrote: This patch is already included in GLIBC 2.20... I can add support for __builtin_trap() but we need preprocessed source and full compile command. You can add -save-temps -v to glibc command to generate these files. I was able to isolate the problem to GLIBC elf/dl-conflict.c and specifically hppa specific elf_machine_rela function called from there. The problem occurs at link time, so crafting a standalone preprocessed source file triggering the error might be difficult, but I'll see what can I do.

[Bug fortran/61847] bug in gfortran runtime: digits cut off when reading floating point number
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61847 Jerry DeLisle jvdelisle at gcc dot gnu.org changed: What|Removed |Added Attachment #33227|0 |1 is obsolete|| --- Comment #20 from Jerry DeLisle jvdelisle at gcc dot gnu.org --- Created attachment 33858 -- https://gcc.gnu.org/bugzilla/attachment.cgi?id=33858action=edit Proposed patch This attached patch enhances gfortran to check the locale and get the currently active decimal character at the time a unit is connected and saves it. During formatted input the decimal type is checked and if necessary changed internally so that the calls to the system provided string to decimal functions convert the value properly. Some configuration checks for locale.h are needed to make sure getting the decimal character will work. If not, the code reverts to the current behavior. Need testing on various platforms for all who can do so. I tested on linux x86-64.
