[PATCH 3/3] MIPS/LD/test: Protected symbol relocation processing
Maciej W. Rozycki
macro@codesourcery.com
Thu Aug 9 01:28:00 GMT 2012
Hi,
This set of test cases complements the protected symbol relocation
processing and IRIX DT_MIPS_OPTIONS processing fixes previously posted.
No failures with the usual set of 23 MIPS targets. OK to apply?
