[patch, fortran] Fix for PR 47676

Hello world, this patch fixes the long-standing bug. A missing temporary causes an invalid read in realloc_on_assign_5.f03 which only becomes noticable when setting MALLOC_CHECK_ or when using valgrind. The bug has three duplicates in the data base, so people keep stumbling across this. I have

[PATCH] Fix loop optimization when ZOL is not available in xtensa configuration

Currently building gcc for xtensa configuration with XCHAL_HAVE_LOOPS set to 0 fails with the following error: xtensa.c:3952: undefined reference to `reorg_loops(bool, hw_doloop_hooks*)' Only compile target-specific zero-overhead loop optimization code when TARGET_LOOPS allows it. 2014-12-30

[PATCH] Instrument bit field and unaligned accesses for TSAN

Hi, I noticed that currently the tsan pass does not instrument bit fileld accesses or unaligned data. Thus some race conditions are not found by the sanitizer. Furthermore the function __tsan_vptr_update is not called with the correct parameters. This patch uses two already existing interfaces

[BUILDROBOT, PATCH] config-list.mk: Extract target name correctly

Hi! With my last change, `sed' is used to cut out the target name from a listed target. Since there may be additional OPTions encoded in the "target", I tried to get only the first submatch before an `OPT'. However, `sed' uses longest match, so I'm re-writing this using awk. If anybody is like

[PATCH][ARM] FreeBSD ARM support, EABI, v3

All, here is the third attempt to support ARM with FreeBSD. In the meantime we found another issue in the unwinder where I had to adapt some stuff. The unwind_phase2_forced function in libgcc calls a stop_fn function. This stop_fn is in FreeBSD's libthr implementation and is called thread_u

Hi, I believe this is breaking bootstrap on aarch64-linux-gnu with kernels <=3.15, 3.16 and above are fine. __kernel_old_{gid,uid}_t were changed in 3.16 from unsigned int to unsigned short. <=3.15 kernel will trigger static asserts in libsanitizer while compiling GCC. I created PR: https://gcc.

For the record, compiling the tests in pr61337 with the patch applied on top of r219099 gives ICEs: use array_list 1 internal compiler error: in gfc_advance_chain, at fortran/trans.c:58 Since this replaces some wrong-code generation by some ICEs, I don’t think this should delay the fix of p

[C++ Patch] PR 58614

Hi, in this ICE on invalid, we crash during error recovery when maybe_adjust_types_for_deduction gets an elt which has TREE_TYPE (elt) == error_mark_node. I think we can simply check for that and return unify_invalid. Tested x86_64-linux. Thanks, Paolo. / /cp 2014-12

[PATCH] Don't check for optab for 16bit bswap

Since 16bit byteswap can be done via an 8 bit rotation (and it is the canonical form), the check for an optab only serves to prevent the bswap optimization for targets that don't have a 16bit byteswap (but do have a rotation instruction). See PR63259 (comments 6 and onwards) for more details. Ch

Hi All, Here is a patch which fixed several performance degradation after operand canonicalization (r216728). Very simple approach is used - if operation is commutative and its second operand required more operations (statements) for computation, swap operands. Currently this is done under special
