* Fix whitespace.Bob Wilson2011-01-131-120/+120
| | | | llvm-svn: 123396
* Fix ARMAsmParser::ParseOperand() to allow it to parse . as a branch target andKevin Enderby2011-01-131-2/+4
| | | | | | directional local labels like 1f and 2b. llvm-svn: 123393
* Speculatively revert r123384 to make llvm-gcc-i386-linux-selfhost buildbot ↵Devang Patel2011-01-132-18/+5
| | | | | | happy. llvm-svn: 123389
* When updating a tSpill/tRestore instruction to be a tSTRr/tLDRr, correctlyJim Grosbach2011-01-131-4/+7
| | | | | | | | | set up the source operands. The original instr has an immediate operand that should be replaced with the frame reg operand rather than just adding the reg operand. Previously, the instruction ended up with too many operands causing an assert() when adding the default predicate. rdar://8825456 llvm-svn: 123387
* Teach MachineBasicBlock::getFirstTerminator to ignore debug values.Jakob Stoklund Olesen2011-01-132-5/+18
| | | | | | | It will still return an iterator that points to the first terminator or end(), but there may be DBG_VALUE instructions following the first terminator. llvm-svn: 123384
* Check for empty structs, and for consistency, zero-element arrays.Bob Wilson2011-01-131-2/+2
| | | | llvm-svn: 123383
* Extend SROA to handle arrays accessed as homogeneous structs and vice versa.Bob Wilson2011-01-131-14/+57
| | | | | | | | | | | | | | | | | This is a minor extension of SROA to handle a special case that is important for some ARM NEON operations. Some of the NEON intrinsics return multiple values, which are handled as struct types containing multiple elements of the same vector type. The corresponding return types declared in the arm_neon.h header have equivalent arrays. We need SROA to recognize that it can split up those arrays and structs into separate vectors, even though they are not always accessed with the same type. SROA already handles loads and stores of an entire alloca by using insertvalue/extractvalue to access the individual pieces, and that code works the same regardless of whether the type is a struct or an array. So, all that needs to be done is to check for compatible arrays and homogeneous structs. llvm-svn: 123381
* Make SROA more aggressive with allocas containing padding.Bob Wilson2011-01-131-34/+27
| | | | | | | SROA only split up structs and arrays one level at a time, so padding can only cause trouble if it is located in between the struct or array elements. llvm-svn: 123380
* Remove some wrong code which fortunately was never executed (as explained inDuncan Sands2011-01-131-6/+9
| | | | | | the comment I added): an extern weak global may have a null address. llvm-svn: 123373
* The most common simplification missed by instsimplify in unoptimized bitcodeDuncan Sands2011-01-131-19/+70
| | | | | | | | is "X != 0 -> X" when X is a boolean. This occurs a lot because of the way llvm-gcc converts gcc's conditional expressions. Add this, and a few other similar transforms for completeness. llvm-svn: 123372
* Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a stepEvan Cheng2011-01-1311-84/+223
| | | | | | | | in the right direction. It eliminated some hacks and will unblock codegen work. But it's far from being done. It doesn't reject illegal expressions, e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all. llvm-svn: 123369
* Experiment with changing the default 32-bit linux stack alignment toEric Christopher2011-01-131-3/+3
| | | | | | 16 bytes for PR8969. Update all testcases accordingly. llvm-svn: 123367
* Keep unnamed_addr when linking.Rafael Espindola2011-01-131-0/+2

* Reject uses of unnamed_addr in declarations.Rafael Espindola2011-01-133-3/+18
| | | | llvm-svn: 123358
* Add a FIXME and two asserts for now in the ARMAsmParser when it sees .code 16 orKevin Enderby2011-01-131-2/+12
| | | | | | | | .code 32 if the TargetMachine's isThumb() boolean does not match. The correct fix is to switch ARM subtargets at that point and is tracked by rdar://8856789 which is bigger task. llvm-svn: 123353

* JimG sez: "The value-kinds look like masks, but they're not consistently usedJason W Kim2011-01-121-2/+2
| | | | | | | | | | | that way, unfortunately. If you want to change them to work additively instead of a one-variant-kind-per-symbolref, that's great and I completely agree it's worth doing, but it really should be a separate patch. Until then, this isn't correct." So I am reverting this bit until a more opportune time. llvm-svn: 123340
* Don't emit a DBG_VALUE for a spill slot that the rewriter decided not to use ↵Jakob Stoklund Olesen2011-01-121-1/+2

* Sometimes, old virtual registers can linger on DBG_VALUE instructions.Jakob Stoklund Olesen2011-01-121-1/+2
| | | | | | Make sure we don't crash in that case, but simply turn them into %noreg instead. llvm-svn: 123335
* Teach VirtRegRewriter to update slot indexes when erasing instructions.Jakob Stoklund Olesen2011-01-121-38/+26
