2013-04-05Fix include guards to match new location.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178877 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-05Don't fetch pointers from a InMemoryStruct.Rafael Espindola
InMemoryStruct is extremely dangerous as it returns data from an internal buffer when the endiannes doesn't match. This should fix the tests on big endian hosts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178875 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-04Don't export symbols in every binary on linux.Rafael Espindola
On freebsd this makes sure that symbols are exported on the binaries that need them. The net result is that we should get symbols in the binaries that need them on every platform. On linux x86-64 this reduces the size of the bin directory from 262MB to 250MB. Patch by Stephen Checkoway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178725 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-03Implements low-level object file format specific output for COFF andEric Christopher
ELF with support for: - File headers - Section headers + data - Relocations - Symbols - Unwind data (only COFF/Win64) The output format follows a few rules: - Values are almost always output one per line (as elf-dump/coff-dump already do). - Many values are translated to something readable (like enum names), with the raw value in parentheses. - Hex numbers are output in uppercase, prefixed with "0x". - Flags are sorted alphabetically. - Lists and groups are always delimited. Example output: ---------- snip ---------- Sections [ Section { Index: 1 Name: .text (5) Type: SHT_PROGBITS (0x1) Flags [ (0x6) SHF_ALLOC (0x2) SHF_EXECINSTR (0x4) ] Address: 0x0 Offset: 0x40 Size: 33 Link: 0 Info: 0 AddressAlignment: 16 EntrySize: 0 Relocations [ 0x6 R_386_32 .rodata.str1.1 0x0 0xB R_386_PC32 puts 0x0 0x12 R_386_32 .rodata.str1.1 0x0 0x17 R_386_PC32 puts 0x0 ] SectionData ( 0000: 83EC04C7 04240000 0000E8FC FFFFFFC7 |.....$..........| 0010: 04240600 0000E8FC FFFFFF31 C083C404 |.$.........1....| 0020: C3 |.| ) } ] ---------- snip ---------- Relocations and symbols can be output standalone or together with the section header as displayed in the example. This feature set supports all tests in test/MC/COFF and test/MC/ELF (and I suspect all additional tests using elf-dump), making elf-dump and coff-dump deprecated.

2013-04-01PNaCl: Allow the ABI checker to be used from "opt"Mark Seaborn
This allows the ABI checker passes to be used in the same way as LLVM's "-verify" pass. It allows the checker to be run between other passes, and without launching pnacl-abicheck as a separate process (so without the overhead of reading bitcode into memory again). Make the ABI checker passes produce fatal errors by default, to match "-verify". This is overridden for pnacl-abicheck's use.

2013-03-28Add a pass to strip bitcode metadata.Jan Voung
This only works on instruction attachments for now. Since it is a ModulePass we can add something to strip NamedMetadata based on a whitelist, if we want to retain some of that.

2013-03-26PNaCl: Add ExpandGetElementPtr pass for converting GetElementPtr to arithmeticMark Seaborn
This is similar to the GEP handling in visitGetElementPtr() in lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp. Once this pass is enabled, it will simplify the language to reduce the set of constructs that a PNaCl translator needs to handle as part of a stable wire format for PNaCl.

2013-03-26Manually update the dependencies in the Makefiles. It turns out that allChandler Carruth
that work on the LLVMBuild based dependency specification didn't actually work, we just now maintain dependencies in *3* places instead of 2. Yay. There may still be some missing dependencies, I'm still sifting through the bots and my builds, but this is a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177988 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-26Split out the IRReader header and the utility functions it provides intoChandler Carruth
its own library. These functions are bridging between the bitcode reader and the ll parser which are in different libraries. Previously we didn't have any good library to do this, and instead played fast and loose with a "header only" set of interfaces in the Support library. This really doesn't work well as evidenced by the recent attempt to add timing logic to the these routines. As part of this, make them normal functions rather than weird inline functions, and sink the implementation into the library. Also clean up the header to be nice and minimal. This requires updating lots of build system dependencies to specify that the IRReader library is needed, and several source files to not implicitly rely upon the header file to transitively include all manner of other headers. If you are using IRReader.h, this commit will break you (the header moved) and you'll need to also update your library usage to include 'irreader'. I will commit the corresponding change to Clang momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177971 91177308-0d34-0410-b5e6-96231b3b80d8

This CL adds a standalone tool pnacl-abicheck for checking the ABI validity of a bitcode file. It also adds a flag pnaclabi-verify to llc to enable the same checking in llc.

2013-03-13Make LTO codegen use a PassManager, rather than a FunctionPassManager, for theLang Hames
codegen passes. This brings it in to line with clang and llc's codegen setup, and tidies up the code. If I understand correctly, adding ModulePasses to a FunctionPassManager is bogus. It only seems to explode if an added ModulePass depends on a FunctionPass though, which might be why this code has survived so long.

2013-03-06Add an RPC to LLC.nexe to init with appended flags (vs set all flags).Jan Voung
This will take the default flags and append any extra flags. For now, this is only intended to support -O in the browser, and perhaps -mcpu=.*, -mattr=. We move the tuning parameters like -mcpu out of the default, so that a user does not end up setting the -mcpu more than once (which is disallowed). What does go into the default is -mtriple, which we may want to hard-code into the build somehow (but it's not yet clear how to do that cleanly). That way, a user does not need to specify that portion. We also hardcode the -sfi-* flags.

This avoids a use of the ParseIR/ParseIRFile API in the sandboxed translator. ParseIR and friends are flexible and handle LLVM .ll parsing. We only need to handle bitcode streams...
