tune-cortexr52: Add hard-float variant

feature-arm-vfp.inc: Allow hard-float on newer simd targets

2024-02-03T21:43:35+00:00

Currently hard-float is dependency upon the special TUNE_CCARGS_MFPU which contains custom -mfpu= values. However, newer 32-bit architectures like cortex-r52 use 'simd' instead. There is no 'simd' entry for -mfpu= according to the GCC manual, it's more or less automatic based on the cpu settings. Add this as an exception to the TUNE_CCARGS_FLOAT setting of hard or softfp.

armv8/armv9: Avoid using -march when -mcpu is chosen

2024-02-02T10:38:28+00:00

Current include logic goes into generic arm v8/v9 architecture tunes and adds corresponding -march option after synthesizing it from various tune fragments, this is fine for a machine which is using armv8/armv9 based tunes but cortex tunes are intentionally using -mcpu option based on selected tune value. So when cortex based default tune is selected for a machine, it will add both -mcpu and -march to the compiler commandline which can result in invalid combinations for this pair in gcc's own logic. This can then result in compiler warnings/errors reporting this e.g. aarch64-yoe-linux-gcc -mcpu=cortex-a72.cortex-a53 -march=armv8-a+crc+crypto -mbranch-protection=standard ... cc1: error: switch '-mcpu=cortex-a72.cortex-a53' conflicts with '-march=armv8-a+crc+crypto' switch and resulted in options '+crc+crypto' being added [-Werror] This is seen in lot of configure test results in glibc 2.39 and the warning is promoted to errors by gcc in some of these checks especially with gcc-14, the logs also show it as warning in other places in configure checks. mcpu option will compute relevant march implicitly as it specifies a cpu implementation and this will be the right value to use, therefore do not specify -march when -mcpu is already describing the cpu.

machine/arch-armv9: remove crc and sve tunes, they are mandatory

2023-12-21T10:38:29+00:00

As per the Arm ARM section A2.3.2, FEAT_CRC32 is mandatory in Armv8.1 onwards, so there's no need to have an explicit optional tune for it. SVE (which was a choice here) and SVE2 (which was not) are both optional with v9.0, but GCC's -march=armv9-a defaults to enabling both SVE and SVE2 on the grounds that there are no implementations of Armv9 that don't support SVE2. This means there's no point having an explicit sve feature as it's enabled out of the box.
