| | | | | | | | The GNU assembler supports prefixing the expression with a '#' to indiciate that the value that is being moved is infact a constant.

* ARM IAS: support GNU extension for ldrd, strdSaleem Abdulrasool2014-01-10
| | | | | | | | | The GNU assembler has an extension that allows for the elision of the paired register (dt2) for the LDRD and STRD mnemonics. Add support for this in the assembly parser.

* [SystemZ] Fix RNSBG bug introduced by r197802Richard Sandiford2014-01-09
| | | | | | | | | The zext handling added in r197802 wasn't right for RNSBG. This patch restricts it to ROSBG, RXSBG and RISBG. (The tests for RISBG were added in r197802 since RISBG was the motivating example.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198862 91177308-0d34-0410-b5e6-96231b3b80d8
* Handle masked rotate amountsRichard Sandiford2014-01-09
| | | | | | | | | | | | | | | At the moment we expect rotates to have the form: (or (shl X, Y), (shr X, Z)) where Y == bitsize(X) - Z or Z == bitsize(X) - Y. This form means that the (or ...) is undefined for Y == 0 or Z == 0. This undefinedness can be avoided by using Y == (C * bitsize(X) - Z) & (bitsize(X) - 1) or Z == (C * bitsize(X) - Y) & (bitsize(X) - 1) for any integer C (including 0, the most natural choice). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198861 91177308-0d34-0410-b5e6-96231b3b80d8
* Match the InstCombine form of rotates by X+CRichard Sandiford2014-01-09
| | | | | | | | | | | | | | | | | | InstCombine converts (sub 32, (add X, C)) into (sub 32-C, X), so a rotate left of a 32-bit Y by X+C could appear as either: (or (shl Y, (add X, C)), (shr Y, (sub 32, (add X, C)))) without InstCombine or: (or (shl Y, (add X, C)), (shr Y, (sub 32-C, X))) with it. We already matched the first form. This patch handles the second too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198860 91177308-0d34-0410-b5e6-96231b3b80d8
