2013-06-24	PNaCl ABI: Strip alignment info from memcpy/memmove/memset intrinsic calls	Mark Seaborn
	Do the same for memcpy/memmove/memset intrinsic calls that we have already done for integer loads and stores: Remove assumptions about pointer alignment by setting the alignment argument to 1. Make the ABI checker require this. BUG=https://code.google.com/p/nativeclient/issues/detail?id=3445 TEST=*.ll tests + PNaCl toolchain trybots Review URL: https://codereview.chromium.org/17563008
2013-06-20	PNaCl ABI: Reduce the set of allowed "align" attributes on loads/stores	Mark Seaborn
	Change the ABI verifier to require "align 1" on non-atomic integer accesses to prevent non-portable behaviour. Allow larger alignments on floating point accesses as a concession to performance, because ARM might not be able to do unaligned FP loads/stores efficiently. Change StripAttributes to make pexes pass the ABI verifier. Also update comments in StripAttributes to match some recent changes.

2013-06-14	PNaCl ABI: Convert "private" linkage to "internal"	Mark Seaborn
	This simplifies the ABI by reducing the number of linkage types we have to check for and represent in the wire format. BUG=https://code.google.com/p/nativeclient/issues/detail?id=3495 TEST=*.ll tests + PNaCl toolchain trybots Review URL: https://codereview.chromium.org/17084003
2013-06-13	PNaCl: Strip more unwanted attributes: "align" on functions and "unnamed_addr"	Mark Seaborn
	Do this stripping in the StripAttributes pass. Change the pass to be a ModulePass so that it can modify global variables. Change the ABI verifier to check this. Also update a comment about "nuw" and "nsw".

2013-06-12	PNaCl ABI: Strip out arithmetic attributes "nsw", "nuw" and "exact"	Mark Seaborn
	"nsw" and "nuw" -- "no signed wrap" and "no unsigned wrap" -- are not used by the backend, which is not surprising because it makes no difference to the hardware if arithmetic overflows. Although "exact" is used by the backend to convert "sdiv exact" to an "ashr" shift, it appears that "sdiv exact" does not get used in practice, and arguably such a transformation belongs in the user toolchain, not the PNaCl translator.

2013-06-06	PNaCl ABI: Strip out calling conventions from functions and calls	Mark Seaborn
	Always use the standard C calling conventions. Disallow "fastcc" etc. BUG=https://code.google.com/p/nativeclient/issues/detail?id=2346 TEST=*.ll tests + PNaCl toolchain trybots Review URL: https://codereview.chromium.org/16529004
2013-06-05	PNaCl ABI: Strip out attributes on functions and function calls	Mark Seaborn
	Add a pass, StripAttributes, for doing this, and enable it. Add an ABI check to reject these attributes.
