[Bug c/23222] gcc optimization error for sparc with xine/ffmpeg, bad assembly generated
--- Additional Comments From ebotcazou at gcc dot gnu dot org 2005-08-04 06:18 --- The test.s file assembles fine on my machine with GNU as 2.16. Could you compile the test.i file with -v and post the command line passed to the assembler? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23222

There was another file a lot more complex that was even worse and only needed -O3 to generate the problem without -fno-inline-functions. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23222

Both can be got by adding -save-temps to the gcc invocation. -- What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|DUPLICATE | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23222
