[PATCH 6/9] x86: operand sizing prefixes can disambiguate insns
Jan Beulich
jbeulich@suse.com
Wed Jun 24 12:13:42 GMT 2020
Use of an explicit data size or REX.W prefix is sufficient indication of
the intended operation when operand size can't be derived from suffix or
register operands. Avoid the ambiguity warning and make in particular
immediate handling (sizing) cope with explicitly specified prefixes.
Extending/reusing the noreg16 test made me notice a few cases of
unintentional 32-bit addressing, which gets corrected at the same time.

* config/tc-i386.c (process_suffix): Skip ambiguous operand size
diagnostic when there is a sizing prefix. Switch to word/dword/
qword encoding when there is a sizing prefix and no (explicit or
derived) suffix.
(update_imm): Handle presence of a sizing prefix.

* testsuite/gas/i386/i386.exp: Run new tests.

Introduce and use pfx* macros.
* testsuite/gas/i386/noreg16.s: Likewise. Replace 32-bit
addressing.
* testsuite/gas/i386/noreg16.d: Adjust expectations.
