| | | | | | | | | | | | | | | | | It's completely unnecessary and can be replace with proper SReg_64 handling instead. This actually fixes a piglit test on SI. v2: use correct register class in addRegisterClass, set special classes as not allocatable v3: revert setting special classes as not allocateable This is a candidate for the stable branch.

| | | | | | | | | | | | | | | | Seems to be allot simpler, and also paves the way for further improvements. v2: rebased on master, use 0 in BUFFER_LOAD_FORMAT_XYZW, use VGPR0 in dummy EXP, avoid compiler warning, break after encoding the first literal. v3: correctly use V_ADD_F32_e64 This is a candidate for the stable branch.

* If bundle alignment is enabled, do not add data to a fragment with instructionsDerek Schuff2013-02-152-4/+7
| | | | | | | | | | | | With bundle alignment, instructions all get their own MCFragments (unless they are in a bundle-locked group). For instructions with fixups, this is an MCDataFragment. Emitting actual data (e.g. for .long) attempts to re-use MCDataFragments, which we don't want int this case since it leads to fragments which exceed the bundle size. So, don't reuse them in this case. Also adds a test and fixes some formatting. llvm-svn: 175316

It also avoids inserting a shift in favor of a trunc, which can be free on some targets. This used to work until LLVM-3.1, but regressed with the 3.2 release. llvm-svn: 175270
* AArch64: add branch fixup pass.Tim Northover2013-02-156-0/+652
| | | | | | | | | | | | | This is essentially a stripped-down version of the ConstandIslands pass (which always had these two functions), providing just the features necessary for correctness. In particular there needs to be a way to resolve the situation where a conditional branch's destination block ends up out of range. This issue crops up when self-hosting for AArch64. llvm-svn: 175269
