* Release build: guard dump functions withManman Ren2012-09-121-1/+1
| | | | | | | | "#if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP)" No functional change. Update r163344. llvm-svn: 163679

* Fix alignment of .comm and .lcomm on mingw32.Benjamin Kramer2012-09-071-2/+4
| | | | | | | | 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 Kramer2012-09-071-6/+5
| | | | | | | | | | | | | - 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

* 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

* Refactor data-in-code annotations.Jim Grosbach2012-05-181-0/+42
| | | | | | | | | | | | | | | | | | | | | | Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 llvm-svn: 157062

* MC: Unknown assembler directives are now hard errors.Jim Grosbach2012-05-011-1/+1
| | | | | | | | | | | | | | | | Previously, an unsupported/unknown assembler directive issued a warning. That's generally unsafe, and inconsistent with the behaviour of pretty much every system assembler. Now that the MC assemblers are mature enough to be the default on multiple targets, it's reasonable to issue errors for these. For target or platform directives that need to stay warnings, we should add explicit handlers for them in, e.g., ELFAsmParser.cpp, DarwinAsmParser.cpp, et. al., and issue the warning there. rdar://9246275 llvm-svn: 155926
* MC: Remove errant EatToEndOfStatement() in asm parser.Jim Grosbach2012-05-011-3/+1
| | | | | | | | | | | | The caller is already responsible for eating any additional input on the line. Putting an additional EatToEndOfStatement() in ParseStatement() causes an entire extra statement to be consumed when treating warnings as errors. For example, test/MC/macros.s will assert() because the .endmacro directive is missed as a result. rdar://11355843 llvm-svn: 155925
* MC assembly parser handling for trailing comma in macro instantiation.Jim Grosbach2012-04-161-5/+5
