* PR12716: PPC crashes on vector compareAdhemerval Zanella2012-10-08
| | | | | | | | | | | | | | | | | | | | Vector compare using altivec 'vcmpxxx' instructions have as third argument a vector register instead of CR one, different from integer and float-point compares. This leads to a failure in code generation, where 'SelectSETCC' expects a DAG with a CR register and gets vector register instead. This patch changes the behavior by just returning a DAG with the vector compare instruction based on the type. The patch also adds a testcase for all vector types llvm defines. It also included a fix on signed 5-bits predicates printing, where signed values were not handled correctly as signed (char are unsigned by default for PowerPC). This generates 'vspltisw' (vector splat) instruction with SIM out of range. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165419 91177308-0d34-0410-b5e6-96231b3b80d8

* Make sure always-inline functions get inlined. <rdar://problem/12423986>Bob Wilson2012-10-07
| | | | | | | | | | | | | | | | Without this change, when the estimated cost for inlining a function with an "alwaysinline" attribute was lower than the inlining threshold, the getInlineCost function was returning that estimated cost rather than the special InlineCost::AlwaysInlineCost value. That is fine in the normal inlining case, but it can fail when the inliner considers the opportunity cost of inlining into an internal or linkonce-odr function. It may decide not to inline the always-inline function in that case. The fix here is just to make getInlineCost always return the special value for always-inline functions. I ran into this building clang with libc++. Tablegen failed to link because of an always-inline function that was not inlined. I have been unable to reduce the testcase down to a reasonable size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165367 91177308-0d34-0410-b5e6-96231b3b80d8
