Reverting until I can figure that out. If anyone's got a reproduction (.s and .o together would be great) - I'd really appreciate it. llvm-svn: 197079

* [PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2013-07-261-2/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch provides basic support for powerpc64le as an LLVM target. However, use of this target will not actually generate little-endian code. Instead, use of the target will cause the correct little-endian built-in defines to be generated, so that code that tests for __LITTLE_ENDIAN__, for example, will be correctly parsed for syntax-only testing. Code generation will otherwise be the same as powerpc64 (big-endian), for now. The patch leaves open the possibility of creating a little-endian PowerPC64 back end, but there is no immediate intent to create such a thing. The LLVM portions of this patch simply add ppc64le coverage everywhere that ppc64 coverage currently exists. There is nothing of any import worth testing until such time as little-endian code generation is implemented. In the corresponding Clang patch, there is a new test case variant to ensure that correct built-in defines for little-endian code are generated. llvm-svn: 187179

* Emit personality function and Dwarf EH data for Win64 SEH.Kai Nacke2013-07-061-5/+10
| | | | | | | | | | | Obviously the personality function should be emitted as language handler instead of the hard coded _GCC_specific_handler. The language specific data must be placed after the unwind information therefore it must not be emitted into a separate section. Reviewed by Charles Davis and Nico Rieck. llvm-svn: 185761
* [SystemZ] Update non-pic DWARF encodingsUlrich Weigand2013-05-061-6/+13
| | | | | | | | | | | | As pointed out by Rafael Espindola, we should match the DWARF encodings produced by GCC in both pic and non-pic modes. This was not the case for the non-pic case. This patch changes all DWARF encodings to DW_EH_PE_absptr for the non-pic case, just like GCC does. The test case is updated to check for both variants. llvm-svn: 181222
* [SystemZ] Define DWARF encodingUlrich Weigand2013-05-061-0/+9
| | | | | | | | | | This is another patch in preparation for adding the SystemZ target. It defines the appropriate values for DWARF encodings; the intent is to be compatible with what GCC currently does on the target. Patch by Richard Sandiford. llvm-svn: 181201

| | | | | | | | | | | | | This finally fixes the encoding. The patch also * Removes eh-frame.ll. It was an unnecessary .ll to .o test that was checking the wrong value. * Merge fde-reloc.s and eh-frame.s into a single test, since the only difference was the run lines. * Don't blindly test the content of the entire .eh_frame section. It makes it hard to anyone actually fixing a bug and hitting a difference in a binary blob. Instead, use a CHECK for each field and document what is being checked. llvm-svn: 178615
* Mips direct object exception handling regressionJack Carter2013-04-011-3/+4
| | | | | | | | | | | | | | | | | 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. llvm-svn: 178506
* Fix the FDE encoding to be relative on ELF.Rafael Espindola2013-03-151-6/+6
| | | | | | | | | | | | 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. llvm-svn: 177141

* Add AArch64 as an experimental target.Tim Northover2013-01-311-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 174054

* PowerPC: EH adjustmentsAdhemerval Zanella2013-01-091-10/+7
| | | | | | | | | 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. llvm-svn: 171979
* PowerPC: Fix eh_frame relocation for PIC Adhemerval Zanella2013-01-041-0/+11

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-1/+1
| | | | | | | | | | | | | | | | | 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. =] llvm-svn: 169131
