Bug ID: 99312
Summary: __ARM_ARCH is not implemented correctly when compiled
with -march=armv8.1-a
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
The latest ACLE dated Q3 2020 has the following for how __ARM_ARCH should be
defined for ARMv8.1-a and above:
For an Arm architecture ArmvX.Y, __ARM_ARCH = X * 100 + Y. E.g.
for Armv8.1 __ARM_ARCH = 801.
----- CUT ----
Currently GCC just does 8.
