The following testcase regressed when SRA started punting on stores to

nonzero means it may not be the lhs of an assignment."

This clean-up patch resolves PR testsuite/104732, the failure of the recent
test gcc.target/i386/pr100711-1.c on 32-bit Solaris/x86. Rather than just

The __register_frame/__deregister_frame functions are used to register
unwinding frames from JITed code in a sorted list. That list itself
is protected by object_mutex, which leads to terrible performance
in multi-threaded code and is somewhat expensive even if single-threaded.

Commits r12-7342 and r12-7344 made some cleanup, leaving

This implements a new module mangling ABI as the original one has a

a) it was not demangleable (oops)
b) implemented a weak ownership model.
This implements a strong ownership model, so that exported entities

PowerPC Darwin8 is the last version to use an unwind frame fallback routine.
This had been omitted from the new shared EH library, along with one more
header dependency that only fires there.

DECL_MD_FUNCTION_CODE() returns an int, on one particular compiler the

Hi!
This adds more correct .machine for most older CPUs. It should be
conservative in the sense that everything we handled before we handle at
least as well now. This does not yet revamp the server CPU handling, it
is too risky at this point in time.
Tested on powerpc64-linux {-m32,-m64}. Also
Good for me, thanks Rasmus.

The std manglings for things like std::string should not apply if
we're not in the global module.

That doesn't work in the case where src is a memory operation. Dest_lo is

On power10, GCC tries to optimize the signed conversion from DImode to
