It lives in gcc/testsuite/lib/target-supports.exp, which is already included
into libgomp/testsuite/lib/libgomp.exp
proc check_effective_target_lto { } {
global ENABLE_LTO
if { [istarget nvptx-*-*] } {
return 0;
}
return [info exists ENABLE_LTO]
}
I'm not sure how it works, but ENABLE_LTO is defined only in gcc/configure.ac .
Maybe it's possible to move it to top-level configure, or to check for "-flto"
support instead.
However, I will be able to fix this only in late Dec, I'm going on vacation
without access to the computer :)
