Bug ID: 111475
Summary: Many C++ analyzer tests FAIL
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: vultkayn at gcc dot gnu.org
Target Milestone: ---
Target: *-*-solaris2.11
Between 20230908 (f9cb357ae962ba2922b8507f4d96227780a063b9) and 20230911
(88a0a883960910530bfefa750461168f539f4a00), man (ca.350 per multilib) analyzer
tests FAIL on Solaris (both 32 and 64-bit, SPARC and x86). There may be a
common pattern (I've only looked at one example):
FAIL: c-c++-common/analyzer/allocation-size-1.c -std=c++14 (test for
warnings, line 33)
FAIL: c-c++-common/analyzer/allocation-size-1.c -std=c++14 note (test for
warnings, line 65)
FAIL: c-c++-common/analyzer/allocation-size-1.c -std=c++14 note at line 21
(test for warnings, line 15)

ISTM that the primary difference is here:
/vol/gcc/src/hg/master/local/gcc/testsuite/c-c++-common/analyzer/allocation-size-1.c:15:37:
note: (1) allocated 42 bytes and assigned to 'int32_t*' {aka 'int*'} here;
'sizeof (int32_t {aka int})' is '4'
vs.
/vol/gcc/src/hg/master/local/gcc/testsuite/c-c++-common/analyzer/allocation-size-1.c:15:37:
note: (1) allocated 42 bytes here
/vol/gcc/src/hg/master/local/gcc/testsuite/c-c++-common/analyzer/allocation-size-1.c:15:37:
note: (2) assigned to 'int32_t*' {aka 'int*'} here; 'sizeof (int32_t {aka
int})' is '4'
i.e. the wording of the note, where the testsuite doesn't cater to the first
form.
This creates an incredible amount of noise, unfortunately.
