Bug ID: 69707
Summary: FAIL: parallel-dims.c test for excess errors with
-flto -fno-use-linker-plugin
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
gcc is called with -fdiagnostics-color=never, but lto1 is called without it:
...
lto1 -quiet -m64 -O2 -fmath-errno -fsigned-zeros -ftrapping-math -fno-trapv
-fno-openmp -foffload-abi=lp64 -fno-diagnostics-show-caret -fopenacc
-ftree-parallelize-loops=32 @/tmp/cc9vUz7t -o parallel-dims.s
...
It seems lto-wrapper drops it.
Running lto1 diagnostics color confuses the 'test for excess errors'.
