With this change, unnecessary comparetf2.c is no longer

libc: switch aarch64 to use softfloat functions from compiler_rt The old definitions in qp.c being all grouped together in one file causes problems when static linking with libgcc (i.e. cc --static-libgcc) due to functions like __trunctfdf2 conflicting with libgcc, as seen in PR 57021 We can also add some missing functions like __fixdfti for converting a double to an int128_t, the lack of which is currently preventing webkit from linking on aarch64, as seen in PR 57022 Unclear to me if libc is the right place for these functions, but we can avoid breaking compatibility right now and maintain the status quo while avoiding some obvious immediate problems. nm output for libc shows no functions being removed by this change.

[PATCH] builtins: remove use of __attribute__((pcs("aapcs"))) on
Windows
Windows does not honour the __attribute__((pcs)) on ARM. Although this will
result in ABI mismatches, compiler-rt should largely be unneeded for resolving
dependencies as we generate MS ABI compliant library calls now for the most
part.

[Builtin] Unxfail tests for armhf
Summary:
Originally, a few tests fail for armhf target due to:
1) COMPILER_RT_ARMHF_TARGET was not set when building the lib
2) COMPILER_RT_ABI should not be defined as `__attribute__((pcs("aapcs")))` for armhf when building for both lib and tests
This addresshttps://bugs.llvm.org//show_bug.cgi?id=32261
mulsc3_test.c is a newly exposed issue, which will be addressed separately.

[PATCH] builtins: expand out the AEABI function stubs
These actually may change calling conventions. We cannot simply provide
function aliases as the aliased function may have a different calling
convention. Provide a forwarding function instead to permit the
compiler to synthesize the calling convention adjustment thunk.
Remove the `ARM_EABI_FNALIAS` macro as that is not safe to use.

[PATCH] [compiler-rt] Add back ARM EABI aliases where legal.
r303188 removed all the uses of aliases for EABI functions from
compiler-rt, because some of them had mismatched calling conventions.
Obviously, we can't use aliases for functions which don't have the same
calling convention, but that's only an issue for floating-point
functions with the hardfloat ABI. In other cases, the stubs increase
size and reduce performance for no benefit.
This patch adds back the aliases, with appropriate checks to make sure
they're only used in cases where the calling convention matches.

Fix ABI mismatch for armhf runtime routines for floating-point arithmetics;
For hard-float arm variants, provide
(1) generic runtime routines with correct calling convention, and
(2) EABI runtime routines at the same time.
I've confirmed that no binary changes for kernels.

Treat aarch64eb the same as aarch64
Restrict usage of m68k assembler versions of {,u}divsi3 and {,u}divsi3 to
kernel and bootloader for 68010.
They requires a special calling convention to udivsi3, and cannot to be
mixed up in normal routines provided by libgcc or compiler_rt. Although,
there's no problem for using them in a controlled situation, i.e., kernel
and standalone programs.
Note that this does not affect at all m68k ports other than sun2, since
codes generated by gcc do not call these routines.
Assembler files are moved from common/lib/libc/arch/m68k/gen to
sys/lib/libkern/arch/m68k in order not to be compiled in libc.

Fix broken printf(3) %d output for numbers more than two digits, e.g.,

Our __{,u}modsi3 codes assume that __udivsi3 returns remainder to

mixing them up results in mess.

Deal with PGO rename.
On sh3 __udivsi3 is gcc "millicode" with special calling convention (less registers clobbered than usual). Each DSO that needs it gets its own hidden copy from libgcc.a. Do not compile udivsi3.c for sh3 here since this C version doesn't conform to what gcc expects and overrides the libgcc.a version. This makes binaries compiled with gcc4.8 work. The issue was not exposed with gcc4.5 since it uses different division strategy by default.
Change remaining "MACHINE_ARCH" to "LIBC_MACHINE_ARCH"
Update compiler-rt glue for the new source layout.
Long double support builds for PPC now.
ARM needs __clear_cache.
Must use LIBC_MACHINE_ARCH for deciding whether 64bit support code is neded. Otherwise e.g. i386 compat libs are broken.
__fixsfdi is required, __fixdfsi already in softfloat.
Use a separate variable for the use of GCC's unwind code.
Don't use aeabi_dcmp.S and aeabi_fcmp.S on ARM yet, softfloat provides the same set of symbols.
Comment out softfloat code until it is decided what to use long term.
__floatunsidf and __floatunsisf are provided by softfloat, but __fixdfdi and __fixdfsi are not. So move them into the corresponding chunks.
Explicitly enumerate platforms that have unwind support to make piecewise migration easier.
Don't build common quad routines if the platform is 64bit since they will not be emitted by the compiler.
Add profiling helper functions to the build.
Don't include bswap for ARM right now, the routines require ARMv6. Separate the soft-float code and don't include it in the libgcc case.
Add ARM (EABI) specific sources. Split off code that requires C11, unwind support in libc or overlaps with soft-float in preparation for using compiler-rt in the non-clang case.
Build glue for including compiler-rt in libc, not hooked up yet.
