2011-07-20Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.Evan Cheng1-16/+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
2011-07-20Add MCObjectFileInfo and sink the MCSections initialization code fromEvan Cheng1-519/+0
TargetLoweringObjectFileImpl down to MCObjectFileInfo. TargetAsmInfo is done to one last method. It's *almost* gone! llvm-svn: 135569
2011-07-19Fix an obvious typo that's preventing x86 (32-bit) from using .literal16.Evan Cheng1-1/+1
llvm-svn: 135535
2011-07-13Fix up TargetLoweringObjectFile ctors to properly initialize fields.Evan Cheng1-0/+41
llvm-svn: 135068
2011-06-23Use the presence of the __compact_unwind section to indicate that a targetBill Wendling1-10/+7
supports compact unwind info instead of having a separate flag indicating this. llvm-svn: 133685
2011-06-22Add a flag that indicates whether a target supports compact unwind info or not.Bill Wendling1-2/+6
llvm-svn: 133662
2011-06-22Add a __LD,__compact_unwind section.Bill Wendling1-0/+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
2011-06-13Fix invalid uses of Twine. Hopefully this fixes the problem that Takumi isRafael Espindola1-7/+7
having. llvm-svn: 132898
2011-06-07Fix a silly error I introduce in r131951.Rafael Espindola1-4/+1
Fixes PR10095. llvm-svn: 132735
2011-05-27Add the suffix to the Win64 EH data sections' names if given. Add a test forCharles Davis1-0/+22
this. XFAIL'd, because the COFF AsmParser can't handle .section yet. llvm-svn: 132220
2011-05-26Revert r132111. I built Release (without Asserts), so I didn't know about theCharles Davis1-2/+0
assert that prevented setting alignment on section creation. llvm-svn: 132113
2011-05-26Align Win64 EH Table sections to 4 bytes.Charles Davis1-0/+2
llvm-svn: 132111
2011-05-24Explain FIXME.Rafael Espindola1-4/+5
llvm-svn: 131952
2011-05-24Fix the defaults for .eh_frame. We were marking it as writable.Rafael Espindola1-2/+2
llvm-svn: 131951
2011-05-20Fix typo. When will I learn?Charles Davis1-1/+0
llvm-svn: 131765
2011-05-20Add .pdata and .xdata sections to the COFF TLOF implementation.Charles Davis1-0/+15
llvm-svn: 131763
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
2011-04-27Remove unnecessary argument.Rafael Espindola1-2/+2
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
2011-04-27Fix indentation.Rafael Espindola1-21/+21
llvm-svn: 130331
2011-04-20Remove unused arguments.Rafael Espindola1-4/+2
llvm-svn: 129844
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
2011-03-19Reapply 127939 since Daniel fixed the breakage. <rdar://problem/9012638>Stuart Hastings1-7/+4
llvm-svn: 127944
2011-03-19Revert 127939. <rdar://problem/9012638>Stuart Hastings1-4/+7
llvm-svn: 127943
2011-03-19Revise r126127 to address Daniel's comments. <rdar://problem/9012638>Stuart Hastings1-7/+4
llvm-svn: 127939
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
2011-02-21Revert r125960, it's breaking darwin10 bootstrap.Eric Christopher1-4/+8
llvm-svn: 126163
2011-02-21Fix to correctly support attribute((section("__DATA, __common"))).Stuart Hastings1-1/+10
Radar 9012638. llvm-svn: 126127
2011-02-18Reapply r114997 now that the buildbots have been updated.Bill Wendling1-8/+4
llvm-svn: 125960
2011-02-14Switch llvm to using comdats. For now always use groups with a singleRafael Espindola1-23/+9
section. llvm-svn: 125526
2011-01-23Delay the creation of eh_frame so that the user can change the defaults.Rafael Espindola1-20/+23
Add support for SHT_X86_64_UNWIND. llvm-svn: 124059
2011-01-23Remove more duplicated code.Rafael Espindola1-29/+29
llvm-svn: 124056
2011-01-23Remove duplicated code.Rafael Espindola1-34/+35

2010-12-10Fixed version of 121434 with no new memory leaks.Rafael Espindola1-1/+1
llvm-svn: 121471
2010-12-10Revert my previous patch to make the valgrind bots happy.Rafael Espindola1-1/+1
llvm-svn: 121461
2010-12-09Initial support for the cfi directives. This is just enough to getRafael Espindola1-1/+1
f: .cfi_startproc nop .cfi_endproc assembled (on ELF). llvm-svn: 121434
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
