2013-10-14The PNaCl bitcode reference manual has moved into the Chromium repository.Eli Bendersky

2013-08-14Updating the developer's guide with additional PNaCl information.Eli Bendersky
I don't think this specific format will be what we eventually "ship" to the NaCl documentation website, but it's useful to have a placeholder to add things to. For example, information like language and library versions supported, preprocessor macros and so on. We will have to document these at some point. Feel free to suggest additional such things that need to be documented (here or in subsequent CLs). BUG=None R=jvoung@chromium.org Review URL: https://codereview.chromium.org/23105006
2013-08-06Rework PNaCl memory orderingJF Bastien
This CL reworks memory ordering as specified by PNaCl. The documentation needed some clarification, and the implementation needs a bit more work around volatile and __sync_synchronize to offer stronger guarantees than what LLVM intends to offer for legacy code. There is a companion patch with Clang changes: https://codereview.chromium.org/22294002 R=eliben@chromium.org TEST= ninja check-all BUG= https://code.google.com/p/nativeclient/issues/detail?id=3475 Review URL: https://codereview.chromium.org/22240002
2013-08-01Add Intrinsic::nacl_atomic_is_lock_freeJF Bastien
This is part of a bigger CL to fix C++11 in PNaCl, to commit in the following order: - https://codereview.chromium.org/20552002 - https://codereview.chromium.org/20554002 - https://codereview.chromium.org/20560002 - https://codereview.chromium.org/20561002 This should be the last PNaCl ABI change for C11/C+11 atomic support. Note that Clang already has a builtin for lock-free, but it's partly resolved by Clang's ExprConstant.cpp and CGBuiltin.cpp, whereas what we want is a call that becomes a constant at translation-time. I made the translation part fairly general so it's easy to support architectures where ``true`` isn't always the right answer.

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).

The stacksave/restore intrinsics are covered by "run_vla_test", tests in GCC torture testsuite, and basic llvm lit tests (mostly related to debug info...). The pow intrinsic is no longer needed after Eli's change to Clang, and pow is done purely in libm (even with -fno-math-errno).

2013-06-24PNaCl ABI: Disallow built-in multiplication in "alloca" instructionsMark Seaborn
Simplify the set of "alloca" instructions the ABI verifier allows. Before this change, we used i8 arrays, such as: alloca [8 x i8] After this change, we will just use i8 with an explicit size value, so that becomes: alloca i8, i32 8 Allocation of variable-length arrays will require an explicit multiply instruction. This means that the code generator no longer has to handle an implicit multiplication in "alloca", reducing the burden on fast-and-simple code generators a little. This means the PNaCl ABI doesn't need to specify whether alloca's implicit multiplication checks for overflow. This doesn't affect what the backend generates. See lib/CodeGen/SelectionDAG/FunctionLoweringInfo.cpp, which handles constant-size AllocaInsts (by filling out StaticAllocaMap) and which is uses for both -O2 (SelectionDAG) and -O0 (FastISel) translation.
