[Bug c++/114772] New: pragma GCC target applied to earlier template function with __attribute__((warn_unused_result))
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114772
Bug ID: 114772
Summary: pragma GCC target applied to earlier template function
with __attribute__((warn_unused_result))
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mjires at gcc dot gnu.org
CC: jamborm at gcc dot gnu.org
Target Milestone: ---
Following minimized testcase fails depending on warn_unused_result attribute.
Fails at least since GCC 10.
$ cat simdjson.cpp
template
inline __attribute__((always_inline))
#ifdef FAIL
__attribute__((warn_unused_result))
#endif
int walk_document(V visitor) {return 0;}
template
void parse_document() {
int r = walk_document(false);
}
void stage2_next() {
parse_document();
}
#pragma GCC target("pclmul")
$ gcc simdjson.cpp -DFAIL
simdjson.cpp: In function ‘void parse_document() [with bool STREAMING = true]’:
simdjson.cpp:6:5: error: inlining failed in call to ‘always_inline’ ‘int
walk_document(V) [with V = bool; bool STREAMING = true]’: target specific
option mismatch
6 | int walk_document(V visitor) {return 0;}
| ^
simdjson.cpp:10:43: note: called from here
10 | int r = walk_document(false);
| ~~^~~
Without __attribute__((warn_unused_result)) it compiles without problems.
Inlining is denied in ix86_can_inline_p, because:
caller: void parse_document() [with bool STREAMING = true]/1
callee: int walk_document(V) [with V = bool; bool STREAMING = true]/2
caller_opts->x_ix86_isa_flags: 000c00110012
callee_opts->x_ix86_isa_flags: 000c00910012
So they differ by OPTION_MASK_ISA_PCLMUL
Source of this difference seems to be attribs.cc:decl_attributes, which is
called during template instantiation, but uses global_options.
