Support for mips32 FPXX
With this patch, MIPS32 Valgrind compiled with -mfpxx can handle all types
(regarding FP_ABI flag) of MIPS32 ELFs.
- Functions arch_elf_pt_proc() and arch_check_elf() are added to elf reader
according to linux/fs/binfmt_elf.c from Linux 4.1;
- Processing .MIPS.abiflags section and initializing appropriate FPU mode for
MIPS32 are added;
- Emulation of prctl(GET/SET_FP_MODE) sys-calls are implemented for MIPS32.
Applying the patch:
patch -p1 < mips_fpxx_full_support.diff
The patch is tested on MIPS32 platforms with Linux 3.13 and 4.1.
Also, there are no regressions on MIPS64.
Regtests need to be performed on other architectures.
