mutex destruction in libgcc/unwind-dw2-fde.c

Hi The unwind code initializes an object_mutex, but it is never destroyed. On VxWorks 5 at least, that's a problem, because it means that module load+unload leaks a resource. I don't know about other VxWorks versions. I'm wondering what the best fix is (insofar as upstream gcc wants to fix it, we

Question on calling possible_polymorphic_call_targets, side effects, and virtual tables.

Hello, I have a SIMPLE_IPA_PASS that parses the program multiple times. As it parses gimple, it builds a data structure with the information collected that will provide some invariants to future iterations over the program. I was looking into adding a new feature that would take advantage of devi

How to run C++ IPA tests?

Hi, I have been adding tests to the gcc/testsuite/gcc.dg/ipa folder successfully for a while now. I am starting to add some tests into gcc/testsuite/g++.dg/ipa now but I am having some issues. 1. Using `make check-g++` returns the following error message "No rule to make target 'check-g++'". 2. W

__builtin_addc support??

79173 – add-with-carry and subtract-with-borrow support (x86_64 and others) (gnu.org) What I find quite interesting is things like this. Since llvm clang provides __builtin_addc __builtin_subc for all targets. Can we provide something similar?

RE: __builtin_addc support??

I just want a portable version of __builtin_addcarry and __builtin_subborrow. Of course if we have things __builtin_rcl and __builtin_rcr would be even better. Sent from Mail for Windows From: Paul Koning Sent: Wedne

[PATCH] Add GNU_PROPERTY_1_GLIBC_2_NEEDED

Motivations: 1. Some binaries which require new ELF features, like DT_RELR, only work with the new glibc binary. They crash at run-time with the older glibc binaries. 2. Somes binaries compiled with the new language features, like C2X printf specifiers, only generate correct results with the new

Re: libgfortran.so SONAME and powerpc64le-linux ABI changes

I've played with some patches to PowerPC to set the defaults for fortran. But without doing a full rebuild like you would do with a new distribution, I think it will be problematical, unless you build everything with the default long double set to IEEE 128-bit. First off all, libquadmath is curre
