- Subject: [PATCH, binutils, Arm] <spec_reg> changes for VMRS and VMSR instructions for Armv8.1-M Mainline
Hi
This patch makes changes to the <spec_reg> operand for VMRS and VMSR
instructions as per the Armv8.1-M Mainline.
New <spec_reg> options to support are:
0b0010: FPSCR_nzcvqc, access to FPSCR condition and saturation flags.
0b1100: VPR, privileged only access to the VPR register.
0b1101: P0, access to VPR.P0 predicate fields
0b1110: FPCXT_NS, enables saving and restoring of Non-secure floating
point context.
0b1111: FPCXT_S, enables saving and restoring of Secure floating point
context.
Testing: Added new test for the valid instruction operands. Testsuite
shows no regression when run for arm-none-eabi targets.
Thanks
Sudi
