Hi
When using ALT_CC/CXX_UNDER_TEST in the compat/struct-layout-1 tests, the c/l
options provided to the “alt” compiler need to avoid latest and greatest GCC
capability. The patch tests to see if the ‘alt’ compiler can handle
-fno-diagnostics-show-line-numbers.
OK for trunk?
thanks
Iain
gcc/testsuite/
* lib/c-compat.exp (compat-use-alt-compiler): handle
-fno-diagnostics-show-line-numbers.
(compat_setup_dfp): Likewise.
