Subject: [Bug testsuite/26950] New: FAIL: gdb.arch/amd64-disp-step-avx.exp: vex2: continue to test_rip_vex2_end
Date: Thu, 26 Nov 2020 12:20:21 +0000 [thread overview]
Message-ID: <bug-26950-4717@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=26950
Bug ID: 26950
Summary: FAIL: gdb.arch/amd64-disp-step-avx.exp: vex2: continue
to test_rip_vex2_end
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: testsuite
Assignee: unassigned at sourceware dot org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
I'm running into:
...
[displaced] displaced_step_restore: restored process 115981 0x400182^M
^M
Program received signal SIGILL, Illegal instruction.^M
test_rip_vex2 () at
/tmp/tdevries/src/gdb/testsuite/gdb.arch/amd64-disp-step-avx.S:40^M
40 vmovsd ro_var(%rip),%xmm0^M
(gdb) FAIL: gdb.arch/amd64-disp-step-avx.exp: vex2: continue to
test_rip_vex2_end
...
The thing being tested here is vex encoding, which is an avx feature:
...
/* Test a VEX2-encoded RIP-relative instruction. */
.global test_rip_vex2
test_rip_vex2:
vmovsd ro_var(%rip),%xmm0
.global test_rip_vex2
test_rip_vex2_end:
nop
...
The cpu has no avx support:
...
$ cat /proc/cpuinfo | grep flags
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm
