| | | | | | | | Now where we used to call ReInitMCSubtargetInfo, we actually recompute the same information as InitMCSubtargetInfo instead of only setting the feature bits. llvm-svn: 164105

| | | | | | | | Apparently, NumSubRegIndices was completely unused before. Adjust it by one to include the null subreg index, just like getNumRegs() includes the null register. llvm-svn: 163628

* Fix alignment of .comm and .lcomm on mingw32.Benjamin Kramer2012-09-075-10/+17
| | | | | | | | For some reason .lcomm uses byte alignment and .comm log2 alignment so we can't use the same setting for both. Fix this by reintroducing the LCOMM enum. I verified this against mingw's gcc. llvm-svn: 163420

* MC: Overhaul handling of .lcommBenjamin Kramer2012-09-076-16/+26
| | | | | | | | | | | | | - Darwin lied about not supporting .lcomm and turned it into zerofill in the asm parser. Push the zerofill-conversion down into macho-specific code. - This makes the tri-state LCOMMType enum superfluous, there are no targets without .lcomm. - Do proper error reporting when trying to use .lcomm with alignment on a target that doesn't support it. - .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2. - Fixes PR13755 (.lcomm crashes on ELF). llvm-svn: 163395

This change adds support for EK_GPRel64BlockAddress for direct object. One fallout from this is to turn on rela relocations for mips64 to match gas. llvm-svn: 162334

* Add `.pushsection', `.popsection', and `.previous' directives to Darwin ASM.Bill Wendling2012-08-081-2/+39
| | | | | | | | | | | | | | | | | | | | There are situations where inline ASM may want to change the section -- for instance, to create a variable in the .data section. However, it cannot do this without (potentially) restoring to the wrong section. E.g.: asm volatile (".section __DATA, __data\n\t" ".globl _fnord\n\t" "_fnord: .quad 1f\n\t" ".text\n\t" "1:" :::); This may be wrong if this is inlined into a function that has a "section" attribute. The user should use `.pushsection' and `.popsection' here instead. The addition of `.previous' is added for completeness. <rdar://problem/12048387> llvm-svn: 161477
* Keep empty assembly macro argument values in the middle of the list.Jim Grosbach2012-07-301-2/+8
| | | | | | | | | | | | | | | | | | | Empty macro arguments at the end of the list should be as-if not specified at all, but those in the middle of the list need to be kept so as not to screw up the positional numbering. E.g.: .macro foo foo_-bash___: nop .endm foo 1, 2, 3, 4 foo 1, , 3, 4 Should create two labels, "foo_1_2_3_4" and "foo_1__3_4". rdar://11948769 llvm-svn: 161002
* Give MCRegisterInfo an implementation file.Jakob Stoklund Olesen2012-07-272-0/+72

* I'm introducing a new machine model to simultaneously allow simpleAndrew Trick2012-07-071-14/+19
| | | | | | | | | | | | | | | | | | | | | | | subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. llvm-svn: 159891
