-Subject: [PATCH] libc: Disable float16 on 32-bit x86 without SSE2
-
-GCC 16 defines __FLT16_MANT_DIG__ when targeting i686 even though
-_Float16 is only usable on x86-32 with SSE2 enabled. The float16
-detection in float16-macros.h keys on that macro, so the shared f16
-math headers are compiled on plain i686 and every use of _Float16
-fails:
-
-  libc/src/__support/FPUtil/BasicOperations.h:63:67:
-      error: SSE register return with SSE2 disabled
-  libc/src/__support/math/acosf16.h:73:14:
-      error: invalid conversion from type '_Float16' without option '-msse2'
-
-Since llvm/lib/Support/APFloat.cpp started including shared/math.h,
-this breaks the LLVM build itself for 32-bit x86 baselines older than
-SSE2 (e.g. -march=pentiumpro), as used by Yocto/OpenEmbedded multilib.
-
-Require SSE2 on 32-bit x86 in the guard, matching the existing
-exclusions for 32-bit Arm and RISC-V. Targets with SSE2 are unaffected.
-
-Upstream-Status: Backport [https://github.com/llvm/llvm-project/commit/05da143c63d333420b99eab198e1a89c97480929]
