[PATCH] Combine location with block using block_locations
Dehao Chen
dehao@google.com
Sat Sep 8 22:26:00 GMT 2012
Hi, Diego,
Thanks a lot for the review. I've updated the patch.
This patch is large and may easily break builds because it reserves
more complete information for TREE_BLOCK as well as gimple_block (may
trigger bugs that was hided when these info are unavailable). I've
done more rigorous testing to ensure that most bugs are caught before
checking in.
* Sync to the head and retest all gcc testsuite.
* Port the patch to google-4_7 branch to retest all gcc testsuite, as
well as build many large applications.
Through these tests, I've found two additional bugs that was omitted
in the original implementation. A new patch is attached (patch.txt) to
fix these problems. After this fix, all gcc testsuites pass for both
trunk and google-4_7 branch. I've also copy pasted the new fixes
(lto.c and tree-cfg.c) below. Now I'd say this patch is in good shape.
But it may not be perfect. I'll look into build failures as soon as it
arises.
Richard and Diego, could you help me take a look at the following two fixes?
Thanks,
Dehao
