* Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.Evan Cheng2011-07-201-16/+0
| | | | | | | There is still a bit more refactoring left to do in Targets. But we are now very close to fixing all the layering issues in MC. llvm-svn: 135611
* Add MCObjectFileInfo and sink the MCSections initialization code fromEvan Cheng2011-07-201-519/+0
| | | | | | | | TargetLoweringObjectFileImpl down to MCObjectFileInfo. TargetAsmInfo is done to one last method. It's *almost* gone! llvm-svn: 135569
* Fix an obvious typo that's preventing x86 (32-bit) from using .literal16.Evan Cheng2011-07-191-1/+1
| | | | llvm-svn: 135535
* Fix up TargetLoweringObjectFile ctors to properly initialize fields.Evan Cheng2011-07-131-0/+41
| | | | llvm-svn: 135068
* Use the presence of the __compact_unwind section to indicate that a targetBill Wendling2011-06-231-10/+7
| | | | | | supports compact unwind info instead of having a separate flag indicating this. llvm-svn: 133685
* Add a flag that indicates whether a target supports compact unwind info or not.Bill Wendling2011-06-221-2/+6
| | | | llvm-svn: 133662
* Add a __LD,__compact_unwind section.Bill Wendling2011-06-221-0/+6
| | | | | | | | If the linker supports it, this will hold the CIE and FDE information in a compact format. The implementation of the compact unwinding emission is coming soon. llvm-svn: 133658
* Fix invalid uses of Twine. Hopefully this fixes the problem that Takumi isRafael Espindola2011-06-131-7/+7

| | | | | | Fixes PR10095. llvm-svn: 132735
* Add the suffix to the Win64 EH data sections' names if given. Add a test forCharles Davis2011-05-271-0/+22
| | | | | | this. XFAIL'd, because the COFF AsmParser can't handle .section yet. llvm-svn: 132220
* Revert r132111. I built Release (without Asserts), so I didn't know about theCharles Davis2011-05-261-2/+0
| | | | | | assert that prevented setting alignment on section creation. llvm-svn: 132113

* Explain FIXME.Rafael Espindola2011-05-241-4/+5

* Fix the defaults for .eh_frame. We were marking it as writable.Rafael Espindola2011-05-241-2/+2
| | | | llvm-svn: 131951
* Fix typo. When will I learn?Charles Davis2011-05-201-1/+0
| | | | llvm-svn: 131765
* Add .pdata and .xdata sections to the COFF TLOF implementation.Charles Davis2011-05-201-0/+15
| | | | llvm-svn: 131763
* Remove a flag that would set the ".eh" symbol as .globl. MachO was the only oneBill Wendling2011-05-051-5/+0
| | | | | | | | who used this flag, and it now emits CFI and doesn't emit this anymore. All other targets left this flag "false". <rdar://problem/8486371> llvm-svn: 130918
* GCC uses a different encoding of pointers in the FDE when usingRafael Espindola2011-05-011-1/+1
| | | | | | -fno-dwarf2-cfi-asm. Implement the same behavior. llvm-svn: 130637

| | | | llvm-svn: 130343
* Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, andRafael Espindola2011-04-271-5/+42
| | | | | | | | | | | | | | | | | | give it a bit more responsibility. Also implement it for MachO. If hacked to use cfi, 32 bit MachO will produce .cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr and 64 bit will produce .cfi_presonality ___gxx_personality_v0 The general idea is that .cfi_personality gets passed the final symbol. It is up to codegen to produce it if using indirect representation (like 32 bit MachO), but it is up to MC to decide which relocations to create. llvm-svn: 130341

* ADT/Triple: Renambe isOSX... methods to isMacOSX for consistency with the OSDaniel Dunbar2011-04-201-1/+1

* CodeGen: Eliminate a use of getDarwinMajorNumber().Daniel Dunbar2011-04-191-11/+3
| | | | | | | | | - There is a minor semantic change here (evidenced by the test change) for Darwin triples that have no version component. I debated changing the default behavior of isOSVersionLT, but decided it made more sense for triples to be explicit. llvm-svn: 129802
* Put each personality function in a section. This fixes the gnu ld warning:Rafael Espindola2011-04-161-0/+33
| | | | | | error in foo.o; no .eh_frame_hdr table will be created. llvm-svn: 129635
* Reapply 127939 since Daniel fixed the breakage. <rdar://problem/9012638>Stuart Hastings2011-03-191-7/+4

| | | | llvm-svn: 127939
* Fix llvm-gcc bootstrap with gnu ld.Rafael Espindola2011-02-241-0/+7
| | | | | | | | | | | The problem was codegen guessing the wrong values and printing .section .eh_frame,"aMS",@progbits,4 It is not clear at all if Codegen should try to guess, MC is the one that should know the default flags. llvm-svn: 126421
* Revert r125960, it's breaking darwin10 bootstrap.Eric Christopher2011-02-211-4/+8

* Delay the creation of eh_frame so that the user can change the defaults.Rafael Espindola2011-01-231-20/+23
| | | | | | Add support for SHT_X86_64_UNWIND. llvm-svn: 124059

* Fixed version of 118639 with an extra assert to catch similar problemsRafael Espindola2010-11-091-1/+1
| | | | | | earlier. Implicit bool -> int conversions are evil! llvm-svn: 118651
* COFF: Add IMAGE_SCN_MEM_READ to text sections.Michael J. Spencer2010-10-271-0/+1
| | | | | | | | There are currently 100 references to COFF::IMAGE_SCN in 6 files and 11 different functions. Section to attribute mapping really needs to happen in one place to avoid problems like this. llvm-svn: 117473
* Fix whitespace.Michael J. Spencer2010-10-271-15/+15
| | | | llvm-svn: 117472
* lib/CodeGen/TargetLoweringObjectFileImpl.cpp: Tweak to emit ↵NAKAMURA Takumi2010-10-191-5/+5
| | | | | | | | ".{section}${name}" instead of ".{section}$linkonce_{name}" for linkonce sections. It seems GNU ld/PECOFF relies on section names, linking with g++'s libstdc++.a would fail. llvm-svn: 116791
* Do not check that the bodies of two defs of same linkonce global are the same.Anton Korobeynikov2010-10-081-1/+1
| | | | | | | Such a check does not make any sense in presense of inlining and other compiler-dependent stuff. This should fix bunch of warnings on mingw32. llvm-svn: 116113
* Revert r114997. It was causing a failure on darwin10-selfhost.Bill Wendling2010-09-281-5/+13
| | | | llvm-svn: 115002
* Fix a FIXME. _foo.eh symbols are currently always exported so that the linkerBill Wendling2010-09-281-13/+5
| | | | | | knows about them. This is not necessary on 10.6 and later. llvm-svn: 114997

| | | | | | | support aligned comm. Detect when compiling for 10.4 and don't emit an alignment for comm. THis will hopefully fix PR8198. llvm-svn: 114817
* two changes:Chris Lattner2010-08-301-5/+0
| | | | | | | | | | | | | 1) nuke ConstDataCoalSection, which is dead. 2) revise my previous patch for rdar://8018335, which was completely wrong. Specifically, it doesn't make sense to mark __TEXT,__const_coal as PURE_INSTRUCTIONS, because it is for readonly data. templates (it turns out) go to const_coal_nt. The real fix for rdar://8018335 was to give ConstTextCoalSection a section kind of ReadOnly instead of Text. llvm-svn: 112496
* fix the definitions of ConstTextCoalSection/ConstDataCoalSectionChris Lattner2010-07-151-2/+3
| | | | | | | | | | | to keep "Text" in sync with the "pure instructions" section attribute. Lack of this attribute was preventing the assembler from emitting multibyte noops instructions for templates (and inlines, and other coalesced stuff) and was causing the assembler to mismatch .o files. This fixes rdar://8018335 llvm-svn: 108461
* Fix a major regression on COFF targets introduced by r103267: 'discardable' ↵Anton Korobeynikov2010-07-061-1/+1
| | | | | | | | section means that it is used only during the program load and can be discarded afterwards. This way *only* debug sections can be discarded, but not the opposite. Seems like the copy-and-pasto from ELF code, since there it contains the reverse flag ('alloc'). llvm-svn: 107658
