Unit	[compiler-rt][ARM] Optimized mulsf3 and divsf3 (#168394) (Reland of #161546, fixing three build and test issues) This commit adds optimized assembly versions of single-precision float multiplication and division. Both functions are implemented in a style that can be assembled as either of Arm and Thumb2; for multiplication, a separate implementation is provided for Thumb1. Also, extensive new tests are added for multiplication and division. These implementations can be removed from the build by defining the cmake variable COMPILER_RT_ARM_OPTIMIZED_FP=OFF. Outlying parts of the functionality which are not on the fast path, such as NaN handling and underflow, are handled in helper functions written in C. These can be shared between the Arm/Thumb2 and Thumb1 implementations, and also reused by other optimized assembly functions we hope to add in future.	8 个月前

lit.cfg.py	Rename config.host_os to config.target_os. config.host_os is derived from CMAKE_SYSTEM_NAME which specifies the target. See: https://cmake.org/cmake/help/latest/variable/CMAKE_SYSTEM_NAME.html To reduce confusion, rename it to config.target_os. The variable name config.target_os was already being used by the Orc tests. Rename it to config.orc_test_target_os with a FIXME to remove.

lit.site.cfg.py.in	[compiler-rt] Rename lit.*.cfg.* -> lit.*.cfg.py.* These lit configuration files are really Python source code. Using the .py file extension helps editors and tools use the correct language mode. LLVM and Clang already use this convention for lit configuration, this change simply applies it to all of compiler-rt.
