--- Comment #16 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2012-01-27 23:20:03 UTC --- Created attachment 26486 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26486 main-loop.c (maybe related from PR52025) This is a small test case from PR52025 generates strange code: It sets up a frame to store a local variable. Notice that there is just one local variable in the whole little program, so there is really no frame needed. This issue can be resolved by -fno-caller-saves, so maybe it's related to the spill fails from here that can also be hacked around with -fno-caller-saves. Maybe this little programs helps to find what's going wrong with the register allocation and spill fails.
