2013-12-04boilerplate for ExpandI64PassAlon Zakai
2013-10-16Add PNaClSjLjEH pass to implement C++ exception handling using ↵Mark Seaborn
setjmp()+longjmp() There are two parts to this: * PNaClSjLjEH.cpp expands out the "invoke", "landingpad" and "resume" instructions, modifying the control flow to use setjmp(). * ExceptionInfoWriter.cpp lowers landingpads' clause lists to data that PNaCl's C++ runtime library will interpret. This part will be reused when we drop the SjLj part and create a stable ABI for zero-cost EH. This pass isn't enabled in PNaClABISimplify yet: I'll do that in a separate change.

2013-09-16Use ARM TTI in "opt" to make up for missing LE32 TTI.Jan Voung
Since we deleted the rewrite of ARM -> LE32 in the bitcode reader, opt is unable to look up a TTI to transform switch(c) { case 1: x = <const1>; break; case 2: x = <const2>; break; ... } into a lookup table to get x from c. This causes a regression in pnacl-llc's size (which has lots of switch statements). Fake the target lookup in opt for now. Eventually we should look into making target info for le32.

2013-07-13Concurrency support for PNaCl ABIJF Bastien
Add portable support for concurrency in PNaCl's ABI: - Promote volatile to atomic. - Promote all memory ordering to sequential consistency. - Rewrite all atomic operations to frozen NaCl intrinsics for pexe. - Rewrite atomic intrinsics to LLVM instructions for translation. This change also adds documentation to the PNaCl language reference, as well as tests where it makes sense. A future CL could clean up more of our code which mentions atomics, volatiles, memory orderings. Multiple reviewers because this is a big patch: - eliben: LLVM-fu and ResolvePNaClIntrinsics. - dschuff: ABI stability. - mseaborn: ABI stability. - sehr: Tron-duty (fight for the user's programs to work).

2013-06-25PNaCl ABI: Disallow various operations on the i1 typeMark Seaborn
Disallow i1 on loads/stores and require the conversions to i8 to be explicit. Add a pass, PromoteI1Ops, that adds the conversions. (Load/store on i1 occur in practice in small_tests for some boolean globals.) Disallow i1 for most arithmetic/comparison operations since these aren't very useful and it's a nuisance for a code generator to have to support these. I haven't seen these occur in practice, but PromoteI1Ops nevertheless expands them. We still allow and/or/xor on i1 because these do occur in practice, and they're less of a nuisance to handle because they never overflow: no truncation to 1 bit is required, unlike with adds. Restrict the type of alloca's argument. Clang always uses i32 here. Disallow i1 in switch instructions. Clang doesn't generate i1 switches for booleans. Move CopyLoadOrStoreAttrs() helper into a header to reuse.

Until there is an intrinsic to *set* the rounding mode, this intrinsic to *get* the rounding mode isn't so useful. Separately we will add a test that for each platform, the initial rounding mode is "1" (round to nearest). That is the case right now for x86, ARM, and MIPS.

2013-05-30PNaCl: Add a pass to expand out Clang's use of registers of struct typeMark Seaborn
Clang's implementation of C++ method pointers generates IR that uses LLVM registers with struct type -- specifically, loads and stores of struct values, and extractvalue instructions. See lib/CodeGen/ItaniumCXXABI.cpp in Clang. Add a pass, ExpandStructRegs, which expands out those uses. Factor out a function from ExpandArithWithOverflow so that the two passes can share some code.

2013-05-28PNaCl: Extend ExpandMulWithOverflow pass to handle uadd.with.overflow tooMark Seaborn
It turned out that umul.with.overflow wasn't the only *.with.overflow intrinsic usage introduced by Clang. I knew that Clang's CGExprCXX.cpp generates umul.with.overflow for an overflow check for C++'s "new Foo[]". The same code for handling "new Foo[]" also generates uadd.with.overflow in some cases. This happens if class Foo has a destructor or a delete[] operator that takes a size argument. In those cases, the C++ ABI adds a "cookie" to the allocation which contains the array's size. Rename the pass to "ExpandArithWithOverflow" and rename files accordingly. Also enable the pass.

2013-05-28Add two passes that implement conversions from PNaCl's specific intrinsicsEli Bendersky
to external function calls during the translation stage (llc). One of the passes is a ModulePass that adds the appropriate function declarations to the module. The other is a FunctionPass that performs the actual call replacement. This split exists because of bitcode streaming. Initially the passes handle the llvm.nacl.{set|long}jmp intrinsics. In the future they may handle additional intrinsics that are part of the PNaCl stable bitcode ABI. This CL also removes the previous approach to handling this conversion (in SelectionDAGBuilder.cpp). That ended up not working - more details in issue 3429. BUG=https://code.google.com/p/nativeclient/issues/detail?id=3429 R=mseaborn@chromium.org Review URL: https://codereview.chromium.org/16047002

2013-05-10PNaCl ABI: Promote illegal integer typesDerek Schuff
This pass (mostly) legalizes integer types by promoting them. It has some limitations (e.g. it can't change function types) but it is more than sufficient for what clang and SROA generate. A more significant limitation of promotion is that packed bitfields of size > 64 bits are still not handled. There are none in our tests (other than callingconv_case_by_case which doesn't require a stable pexe) but we will want to either handle them by correctly expanding them, or find a better way to error out.

This pass expands out the "byval" and "sret" argument attributes. This will affect the calling conventions for PPAPI under PNaCl (for passing PP_Var etc. by value), so the PNaCl PPAPI shims will need to be updated in order to enable this pass by default.

2013-04-23PNaCl: Add FlattenGlobals pass for simplifying global variable initializersMark Seaborn
This pass converts initializers for global variables into a flattened normal form which removes nested struct types and simplifies ConstantExprs. In the future, we might change the bitcode format to use the flattened bytes+relocs representation for global initializers. In that case, we will be able to reuse the FlattenedConstant class in the bitcode reader/writer for converting to and from this form.

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).

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
