2013-04-01Mips direct object exception handling regressionJack Carter
Revision 177141 caused a regression in all but mips64 little endian. That is because none of the other Mips targets had test cases checking the contents of the .eh_frame section. This patch fixes both the llvm code and adds an assembler test case to include the current 4 flavors. The test cases unfortunately rely on llvm-objdump. A preferable method would be to use a pretty printer output such as what readelf -wf <elf_file> would give. I also changed the name of the test case to correct a typo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178506 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-15Fix the FDE encoding to be relative on ELF.Rafael Espindola
This is a very late complement to r130637 which fixed this on x86_64. Fixes pr15448. Since it looks like that every elf architecture uses this encoding when using cfi, make it the default for elf. Just exclude mips64el. It has a lovely .ll -> .o test (ef_frame.ll) that tests that nothing changes in the binary content of the .eh_frame produced by llc. Oblige it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177141 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-31Add AArch64 as an experimental target.Tim Northover
This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174054 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15Split address information for DWARF5 split dwarf proposal. This involvesEric Christopher
using the DW_FORM_GNU_addr_index and a separate .debug_addr section which stays in the executable and is fully linked. Sneak in two other small changes: a) Print out the debug_str_offsets.dwo section. b) Change form we're expecting the entries in the debug_str_offsets.dwo section to take from ULEB128 to U32. Add tests for all of this in the fission-cu.ll test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172578 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09PowerPC: EH adjustmentsAdhemerval Zanella
This patch adjust the r171506 to make all DWARF enconding pc-relative for PPC64. It also adds the R_PPC64_REL32 relocation handling in MCJIT (since the eh_frame will not generate PIC-relative relocation) and also adds the emission of stubs created by the TTypeEncoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171979 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-04PowerPC: Fix eh_frame relocation for PIC Adhemerval Zanella
This patch fixes the PPC eh_frame definitions for the personality and frame unwinding for PIC objects. It makes PIC build correctly creates relative relocations in the '.rela.eh_frame' segments and thus avoiding a text relocation that generates a DT_TEXTREL segments in link phase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171506 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Don't lazily allocate eh_frame. We're not lazily allocating things like the ↵David Chisnall
LSDA, which are only used when the eh frame is used, so this lazy allocation doesn't really make sense.
