Bug ID: 71455 Summary: On files with many functions, gcc 4.8.3 is much slower than v4.4.5 Product: gcc Version: 4.8.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: avibl at cadence dot com Target Milestone: --- Created attachment 38662 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=38662&action=edit compressed tar file with C code and gcc -v output We’ve recently upgraded from gcc 4.4.5 to 4.8.3 and we noticed that for files with a large amount of functions compiling with version 4.8.3 is almost an order of magnitude slower than 4.4.5. This is even without the optimizer. Attached is an example of such a file and the output of gcc -v with the 2 versions. Thanks
