The test case "gcc/testsuite/gcc.dg/hoist-register-pressure.c" is
failed on x86_64-apple-darwin because it uses more registers than

registers.
Tested on x86_64-apple-darwin/x86_64-linux, is it OK?
I'd say it is better to do the scan-rtl-dump only on nonpic targets, that
way
it won't be done on darwin or for testing with --target_board=unix/-fpic
where
it would fail too. You can add the test with smaller register pressure as
a
new test (hoist-register-pressure2.c).
Hi Jakub,
Thanks for the suggestion. Updated patch as attached. Now it can work with
-fPIC/-fno-PIC options.
Tested on x86_64-apple-darwin/x86-linux, is it OK.
Thanks
