2011-05-05Remove a flag that would set the ".eh" symbol as .globl. MachO was the only oneBill Wendling1-5/+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
2011-05-01GCC uses a different encoding of pointers in the FDE when usingRafael Espindola1-1/+1
-fno-dwarf2-cfi-asm. Implement the same behavior. llvm-svn: 130637

llvm-svn: 130343
2011-04-27Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, andRafael Espindola1-5/+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

2011-04-20ADT/Triple: Renambe isOSX... methods to isMacOSX for consistency with the OSDaniel Dunbar1-1/+1
triple component. llvm-svn: 129838
2011-04-19CodeGen: Eliminate a use of getDarwinMajorNumber().Daniel Dunbar1-11/+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
2011-04-16Put each personality function in a section. This fixes the gnu ld warning:Rafael Espindola1-0/+33
error in foo.o; no .eh_frame_hdr table will be created. llvm-svn: 129635

2011-02-24Fix llvm-gcc bootstrap with gnu ld.Rafael Espindola1-0/+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

2010-11-09Fixed version of 118639 with an extra assert to catch similar problemsRafael Espindola1-1/+1
earlier. Implicit bool -> int conversions are evil! llvm-svn: 118651
2010-10-27COFF: Add IMAGE_SCN_MEM_READ to text sections.Michael J. Spencer1-0/+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
2010-10-27Fix whitespace.Michael J. Spencer1-15/+15
llvm-svn: 117472
2010-10-19lib/CodeGen/TargetLoweringObjectFileImpl.cpp: Tweak to emit ↵NAKAMURA Takumi1-5/+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
2010-10-08Do not check that the bodies of two defs of same linkonce global are the same.Anton Korobeynikov1-1/+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
2010-09-28Revert r114997. It was causing a failure on darwin10-selfhost.Bill Wendling1-5/+13
llvm-svn: 115002
2010-09-28Fix a FIXME. _foo.eh symbols are currently always exported so that the linkerBill Wendling1-13/+5
knows about them. This is not necessary on 10.6 and later. llvm-svn: 114997
2010-09-27the latest assembler that runs on powerpc 10.4 machines doesn'tChris Lattner1-0/+14
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
2010-08-30two changes:Chris Lattner1-5/+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
2010-07-15fix the definitions of ConstTextCoalSection/ConstDataCoalSectionChris Lattner1-2/+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
2010-07-06Fix a major regression on COFF targets introduced by r103267: 'discardable' ↵Anton Korobeynikov1-1/+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
2010-07-01MC: Move COFF enumeration constants to llvm/Support/COFF.h, patch by MichaelDaniel Dunbar1-55/+55
Spencer! llvm-svn: 107418
2010-06-29Revert r107205 and r107207.Bill Wendling1-4/+3
llvm-svn: 107215
2010-06-29Introducing the "linker_weak" linkage type. This will be used for Objective-CBill Wendling1-3/+4
metadata types which should be marked as "weak", but which the linker will remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". llvm-svn: 107205
