Description Rainer Orth 2024-02-28 13:27:02 UTC 
Two tests FAIL on 32 and 64-bit Solaris/x86 with the native asembler in use:

FAIL: gcc.target/i386/avx512cd-vpbroadcastmb2q-2.c (test for excess errors)
UNRESOLVED: gcc.target/i386/avx512cd-vpbroadcastmb2q-2.c compilation failed to produce executable
FAIL: gcc.target/i386/avx512cd-vpbroadcastmw2d-2.c (test for excess errors)
UNRESOLVED: gcc.target/i386/avx512cd-vpbroadcastmw2d-2.c compilation failed to produce executable

Excess errors: 
Assembler: avx512cd-vpbroadcastmb2q-2.c
        "/var/tmp//ccs_9lod.s", line 42 : Invalid instruction argument
        Near line: "    vpbroadcastmb2q %k0, %zmm0"

Assembler: avx512cd-vpbroadcastmw2d-2.c
        "/var/tmp//ccevT6Rd.s", line 35 : Invalid instruction argument
        Near line: "    vpbroadcastmw2d %k0, %zmm0"

I suspect this is just an as bug.

While I thought about adding tests for the two vpbroadcastm* insns to
check_effective_target_avx512cd to guard against this, it's probably best to
just xfail the tests on Solaris/x86 with as, especially since the native
assembler isn't seeing any more fixes these days.

    testsuite: i386: Skip gcc.target/i386/avx512cd-vpbroadcastmb2q-2.c etc. with Solaris as [PR114150]
    
    Two avx512cd tests FAIL to assemble with the Solaris/x86 assembler:
    
    FAIL: gcc.target/i386/avx512cd-vpbroadcastmb2q-2.c (test for excess errors)
    UNRESOLVED: gcc.target/i386/avx512cd-vpbroadcastmb2q-2.c compilation failed
    to produce executable
    FAIL: gcc.target/i386/avx512cd-vpbroadcastmw2d-2.c (test for excess errors)
    UNRESOLVED: gcc.target/i386/avx512cd-vpbroadcastmw2d-2.c compilation failed
    to produce executable
    
    Excess errors:
    Assembler: avx512cd-vpbroadcastmb2q-2.c
            "/var/tmp//ccs_9lod.s", line 42 : Invalid instruction argument
            Near line: "    vpbroadcastmb2q %k0, %zmm0"
    
    Assembler: avx512cd-vpbroadcastmw2d-2.c
            "/var/tmp//ccevT6Rd.s", line 35 : Invalid instruction argument
            Near line: "    vpbroadcastmw2d %k0, %zmm0"
    
    This seems to be an as bug, but given that this rarely if ever gets any
    fixes these days, this test just skips the affected tests.
    
    Adjuststing check_effective_target_avx512cd instead doesn't seem
    sensible since it would disable quite a number of working tests.
    
    Tested on i386-pc-solaris2.11 (as and gas) and x86_64-pc-linux-gnu.

Fixed for GCC 14.0.1.
