2012-09-07Fix alignment of .comm and .lcomm on mingw32.Benjamin Kramer5-10/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163420 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-07MC: Overhaul handling of .lcommBenjamin Kramer6-16/+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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163395 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-22For mips64 switch statements in subroutines could generate Jack Carter1-3/+9
within the codegen EK_GPRel64BlockAddress. This was not supported for direct object output and resulted in an assertion. 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162334 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-08Fix for .pdata and .xdata section attributes on COFF.Anton Korobeynikov2-8/+4
Patch by kai@redstar.de ! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161487 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-08Add `.pushsection', `.popsection', and `.previous' directives to Darwin ASM.Bill Wendling1-2/+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> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161477 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-30Keep empty assembly macro argument values in the middle of the list.Jim Grosbach1-2/+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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161002 91177308-0d34-0410-b5e6-96231b3b80d8
