| | | | | This fix was noted in the comments to bug 6851, but for some reason it was not applied when originally committed.

* PR4886: check build-id if able.Wenji Huang2008-10-061-0/+40
| | | | This provides sanity check of debuginfo file based on build-id. Many cases are considered, whether build-id exists in debuginfo file or not, whether module is loaded or not, whether build-id exists in runtime kernel/module. It will do work when LD >= 2.18 and kernel >=2.6.23, otherwise no check.

Add functioncallcount.meta and functioncallcount.stp. Add para-callgraph.stp and para-callgraph.meta. Fixed __stp_get_mm_path() error return code. diagnostics improvement: print arch/mach at top if -vv Make _vfs.generic_commit_write only for kernel<=2.6.25 Handles "mortally wounded" threads correctly when detaching. further clarify that elfutils need not be absolutely freshest, nor rebuilt every time point out releases/ directory; clarify optionality of elfutils bundling Add auto_free_ref to auto_free stuff; bug 6694
