- Subject: [PATCH 2/2, AArch64] change the gas verbose error reporting on by default
- Authentication-results: sourceware.org; auth=none
For AArch64 advanced SIMD assembly coding, there are some constraints
on operand formats. For some instructions, only specific subtypes are
accepted.
Take "fcvtn" for example,
without verbose error
==
./as-new -mno-verbose-error -o 2.o 2.s
2.s: Assembler messages:
2.s:1: Error: operand mismatch -- `fcvtn v25.4s,v26.4s'
with verbose error
==
./as-new -mverbose-error -o 2.o 2.s
2.s: Assembler messages:
2.s:1: Error: operand mismatch -- `fcvtn v25.4s,v26.4s'
2.s:1: Info: did you mean this?
2.s:1: Info: fcvtn v25.4h,v26.4s
2.s:1: Info: other valid variant(s):
2.s:1: Info: fcvtn v25.2s,v26.2d
More heuristic and helpful messages are delivered to user.
This patch set verbose error default on for AArch64, and basically, only
SIMD error report affected. I also run through gcc, gdb testsuite, no
testcase affected.
Please review.
Thanks
Jiong
gas/
* config/tc-aarch64.c (aarch64_opts): Add new option "mno-verbose-error".
(verbose_error_p): Initialize to 1.
* doc/c-aarch64.texi (AArch64 Options): Document -mverbose-error and
-mno-verbose-error.
gas/testsuite/
* gas/aarch64/illegal.d: Pass -mno-verbose-error.
* gas/aarch64/verbose-error.s: Add more verbose message testcases.
* gas/aarch64/verbose-error.l: Ditto.
