- Subject: [patch 1/3] Code cleanup: gdb.threads/gcore-thread.exp
Hi,
proc load_core is later used by patch 2/3.
I will check it in when the other two patches are considered ready.
No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.
Thanks,
Jan

* gdb.threads/gcore-thread.exp ($testfile): Match it the .exp
filename.
($srcfile): Preserve the original value.
($testfile): Match it the .exp filename.
($corefile): New variable. Substitute it around.
Use clean_restart. Substitute
(load_core): Move core loading into this proc.
Fix restore of $timeout if load_core fails.
