Rainer Orth 1e56821bac [Linux] Hack around Linux/sparc <bits/stdio-ldbl.h>
I've been using this hack to work around the Linux/sparc64 compile failure
described in Issue #47994
<https://github.com/llvm/llvm-project/issues/47994>, especially since the
underlying glibc PR build/27558
<https://sourceware.org/bugzilla/show_bug.cgi?id=27558> doesn't seem to be
making progress and some fix is required to have LLVM build on
`sparc64-unknown-linux-gnu` at all, as evidenced on the buildbot.

Tested on `sparc64-unknown-linux-gnu`.

Zahira Ammarguellat cec7c2b32e Revert "[CLANG][PATCH][FPEnv] Add support for option -ffp-eval-method and extend #pragma float_control similarly"
The intent of this patch is to add support of -fp-model=[source|double|extended] to allow
the compiler to use a wider type for intermediate floating point calculations. As a side
effect to that, the value of FLT_EVAL_METHOD is changed according to the pragma
float_control.
Unfortunately some issue was uncovered with this change in preprocessing. See details in
https://reviews.llvm.org/D93769 . We are therefore reverting this patch until we find a way
to reconcile the value of FLT_EVAL_METHOD, the pragma and the -E flow.

This reverts commit 66ddac22e2.

Defining the macro will help minimize porting pain for existing code compiled with xlc/xlC. xlC never shipped cross-compiling support, so the difference is not observable anyway.

Sam Clegg d1a96e906c [clang][emscripten] Reduce alignof long double from 16 to 8 bytes
This means `max_align_t` is 8 bytes which also sets the alignment
malloc.  Since this is technically and ABI breaking change we have
limited to just the emscripten OS target.  It is also relatively low
import breakage since it will only effect the alignement of struct that
contai `long double`s (extremerly rare I imagine).

Emscripten's malloc implementation already use 8 byte alignement
(dlmalloc uses and alignement of 2*sizeof(void*) == 8 rather than
checking max_align_t) so will not be effected by this change.  By
bringing the ABI in line with the current malloc code this will fix
several issue we have seen in the wild.

   Tweaks the changes made in:

2. Move section name validation code added (long ago) in commit 30ba67439 out
   of libBasic into Sema and base the check on the triple. This is a bit less
   OOP-y, but completely in line with what we do in many other places in Sema.
