Summary:
- Problem occurs when:
-- 32-bit inferiors run on x86_32 machine and
the architecture doesn't have AVX feature
-- This causes FPRType to be set to eFPRTypeFXSAVE
-- PTRACE_GETFPREGS was being used to read FXSAVE area
-- For 32-bit inferiors running on x86_32 machine,
PTRACE_GETFPREGS reads FSAVE area and not FXSAVE area
- Changed ptrace API to PTRACE_GETREGSET for 32-bit inferiors
-- This reads FPR data in FXSAVE format.
-- For 64-bit inferiors, no change has been made.
- Modified XFAIL for TestReturnValue.py
-- Earlier, this test was passing for Linux OS
-- Now, it passes for Android OS as well
