Subject: [PATCH] testsuite: Make check-function-bodies work with LTO
This patch tries to make check-function-bodies automatically
choose between reading the regular assembly file and reading the
LTO assembly file. There should only ever be one right answer,
since check-function-bodies doesn't make sense on slim LTO output.
Maybe this will turn out to be impossible to get right, but I'd like
to try at least.
gcc/testsuite/
* lib/scanasm.exp (check-function-bodies): Look in ltrans0.ltrans.s
if the test appears to be using LTO.
