Bug ID: 82920
Summary: cet test failures on darwin
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: dominiq at lps dot ens.fr
CC: hjl at gcc dot gnu.org, iains at gcc dot gnu.org
Target Milestone: ---
The following tests are failing on x86_64-apple-darwin16 with both -m32 and
-m64:
FAIL: g++.dg/cet-notrack-1.C -std=gnu++11 scan-assembler-times \\tcall[
\\t]+puts 2 (found 0 times)
FAIL: g++.dg/cet-notrack-1.C -std=gnu++14 scan-assembler-times \\tcall[
\\t]+puts 2 (found 0 times)
FAIL: g++.dg/cet-notrack-1.C -std=gnu++98 scan-assembler-times \\tcall[
\\t]+puts 2 (found 0 times)
FAIL: gcc.target/i386/cet-notrack-icf-1.c scan-assembler set[ \\t]+fn2,fn1
FAIL: gcc.target/i386/cet-notrack-icf-1.c scan-assembler set[ \\t]+fn3,fn1
FAIL: gcc.target/i386/cet-notrack-icf-2.c scan-assembler set[ \\t]+fn2,fn1
FAIL: gcc.target/i386/cet-notrack-icf-3.c scan-assembler set[ \\t]+fn2,fn1
FAIL: gcc.target/i386/cet-notrack-icf-3.c scan-assembler set[ \\t]+fn3,fn1
FAIL: gcc.target/i386/cet-notrack-icf-4.c scan-assembler set[ \\t]+fn3,fn1
FAIL: gcc.target/i386/cet-sjlj-3.c scan-assembler-times call\\tlongjmp 1 (found
0 times)
FAIL: gcc.target/i386/cet-sjlj-5.c scan-assembler-times call\\tlongjmp 1 (found
0 times)
In addition the following tests fail with -m32:
FAIL: gcc.target/i386/cet-notrack-5a.c scan-assembler-not \\tcall[ \\t]+
FAIL: gcc.target/i386/cet-notrack-5b.c scan-assembler-times \\tcall[ \\t]+ 1
(found 2 times)
FAIL: gcc.target/i386/cet-notrack-6b.c scan-assembler-not \\tcall[ \\t]+
The following patch fixes the corresponding tests, but I have no idea about
what to do with the others:
