These are the latest results from uClibc tool chain testing. Tests have been carried out using Or1ksim running Linux as a target. For performance reasons, the tests have been heavily parallelized (beyond the level in the standard GNU scripts), and the results combined.
Unless otherwise indicated, the tools (and libraries and Linux) are the SVN or git versions on the date shown, and record the number of tests in each [[test result category]]. For each tool an explanation is provided of any tests with a FAIL, XPASS or UNRESOLVED outcome.

==== FAIL tests ====
;gcc.dg/attr-weakref-1.c (test for excess errors)
:Fails in upstream as well. The problem seems to be that a weakref to a weakref isn't emitted in the asm output.
;gcc.dg/builtin-object-size-10.c scan-tree-dump objsz "maximum object size 21"
:Needs investigation.
;gcc.dg/c99-stdint-1.c (test for excess errors)
:Problem here seems to be that uClibc defines WCHAR_MIN to (-2147483647 - 1) and WCHAR_MAX to (2147483647), but __WCHAR_TYPE__ is defined to be unsigned int
;gcc.dg/c99-stdint-7.c (test for excess errors)
:Fails because WCHAR_MIN != __WCHAR_MIN__
;gcc.dg/lower-subreg-1.c scan-rtl-dump subreg1 "Splitting reg"
:This has to do with splitting large types into registers.
:According to the link below, lower subreg has changed upstream.
:https://blueprints.launchpad.net/gcc-linaro/+spec/investigate-lowersubreg
:This regression was not present in: GCC: (GNU) 4.8.0 20120303 (experimental), so it seems likely the upstream change is related.
:Assembly looks correct, but inefficient.
