The testcase is very similiar. The first one needs -fno-tree-ccp, the second one fails with just -O. The testcase for PR46165 crashes in 4.4 with following message: $ gcc -O -fno-tree-ccp pr46165.c pr46165.c: In function 'g': pr46165.c:2: error: control flow in the middle of basic block 2 pr46165.c:2: internal compiler error: verify_flow_info failed Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. With the attached testcase, however, it crashes with a different message: $ gcc -O testcase.c testcase.c:1: warning: data definition has no type or storage class testcase.c: In function 'g': testcase.c:4: warning: initialization from incompatible pointer type testcase.c:6: error: verify_flow_info: Incorrect fallthru 3->4 testcase.c:6: error: wrong insn in the fallthru edge (barrier 7 6 16) testcase.c:6: internal compiler error: in rtl_verify_flow_info, at cfgrtl.c:2067 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Tested revisions: 4.4 r166509 - crash (with yes,rtl,df checking) ^ permalink raw reply [flat|nested] 5+ messages in thread
