2013-11-21Clean up handling of PNaCl bitcode headers.Karl Schimpf
Write out all of PNaCl bitcode headers using a single interface function. BUG= https://code.google.com/p/nativeclient/issues/detail?id=3720 R=jvoung@chromium.org Review URL: https://codereview.chromium.org/61753017
2013-11-21Fixes the modeling of type ids within PNaCl bitcode files.Karl Schimpf
The code previously was very inconsisted in modeling the number of bits needed for type ids within abbreviations. Frequently, the number of bits used was based on the total number of types. This is a bad choice in that this includes all function types, even though most cases do not use these types. This patch makes the selection more consistent. Also removing TYPE_CODE_ARRAY, since it is not allowed. BUG= https://code.google.com/p/nativeclient/issues/detail?id=3720 R=jvoung@chromium.org Review URL: https://codereview.chromium.org/68503018
2013-11-20Remove UseRelativeID branching from NaClBitcodeReader, assume true.Jan Voung
This was kept in upstream LLVM for backwards compatibiilty with version 0 bitcode, but PNaCl only accepts version 1 bitcode, so UseRelativeID is always true. This reduces the number of branches taken while llvm-dis'ing the Ogre SampleBrowser from 2,680,184,988 branches to 2,670,798,955 branches. A 2.5% difference in wall-clock time...

2013-11-15PNaCl: Change exception info format to distinguish catch-all/cleanup clausesMark Seaborn
The initial version of ExceptionInfoWriter.cpp encodes a landingpad's "cleanup" clause the same as "catch i8* null" (a catch-all). But it turns out we do want to distinguish these two: If an uncaught exception occurs, we don't want the runtime to run C++ destructors (cleanups), because this involves unwinding the stack to jump to landingpads, which loses the context of where the uncaught exception was thrown from, which is unhelpful for debugging. (The C++ standard says it's optional whether destructors are run when an uncaught exception occurs.) So, change the encoding as follows: * Use 0 as the ID for "cleanup" clauses. * Add 1 to the IDs of types and "catch" clauses. (Adding 1 to both seems neater than just one of them.) * This means we can use 0 for the terminator of filter lists instead of -1, which seems a little neater. This requires a corresponding change to eh_pnacl.cc in libsupc++.
