Bug ID: 101045
Summary: config/i386/subst.md: 76: possible cut'n'paste error ?
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
I am a novice at Coverity, but it says:
*** CID 1485952: Incorrect expression (COPY_PASTE_ERROR)
/root/gcc-coverity/gcc/config/i386/subst.md: 76 in recog_97(rtx_def *, rtx_insn
*, int *)()
70 (match_operand:SUBST_V 1))]
71 "TARGET_AVX512F"
72 [(set (match_dup 0)
73 (vec_merge:SUBST_V
74 (match_dup 1)
75 (match_operand:SUBST_V 2 "nonimm_or_0_operand" "0C")
>>> CID 1485952: Incorrect expression (COPY_PASTE_ERROR)
>>> "pattern1062" in "pattern1062(x2, E_V8DImode, E_V16DImode)" looks like a copy-paste error.
76 (match_operand:<avx512fmaskmode> 3 "register_operand" "Yk")))])
My best guess is that the 3 should be a smaller number. Advice sought.

subst.md is just fine, and it is unclear why Coverity thinks there is any copy
and paste error, this is all generated code and matches what should be
generated.

#line 71 "/home/apinski/src/upstream-gcc-git/gcc/gcc/config/i386/subst.md"
(TARGET_AVX512F))
return -1;
return 3191; /* avx512f_alignv8di_mask */
case E_V4DImode:
if (pattern334 (x2, E_V4DImode, E_QImode) != 0
|| !(
#line 71 "/home/apinski/src/upstream-gcc-git/gcc/gcc/config/i386/subst.md"
(TARGET_AVX512F) && (
#line 10090 "/home/apinski/src/upstream-gcc-git/gcc/gcc/config/i386/sse.md"
(TARGET_AVX512F) &&
#line 333 "/home/apinski/src/upstream-gcc-git/gcc/gcc/config/i386/sse.md"
(TARGET_AVX512VL))))
return -1;
Yes this is generated code so having TARGET_AVX512F twice will happen.
Also I am not shocked at coverity also getting the lines wrong with the
expression over multiple lines.
