Tim Northover 3e61ccdded CodeGen: extend f16 conversions to permit types > float. 
This makes the two intrinsics @llvm.convert.from.f16 and
@llvm.convert.to.f16 accept types other than simple "float". This is
only strictly needed for the truncate operation, since otherwise
double rounding occurs and there's no way to represent the strict IEEE
conversion. However, for symmetry we allow larger types in the extend
too.

During legalization, we can expand an "fp16_to_double" operation into
two extends for convenience, but abort when the truncate isn't legal. A new
libcall is probably needed here.

Even after this commit, various target tweaks are needed to actually use the
extended intrinsics. I've put these into separate commits for clarity, so there
are no actual tests of f64 conversion here.

Argument.h Add 'nonnull', a new parameter and return attribute which indicates that the pointer is not null. Instcombine will elide comparisons between these and null. Patch by Luqman Aden! 2014-05-20 01:23:40 +00:00
AssemblyAnnotationWriter.h Move the LLVM IR asm writer header files into the IR directory, as they 2014-01-07 12:34:26 +00:00
Attributes.h Add a new attribute called 'jumptable' that creates jump-instruction tables for functions marked with this attribute. 2014-06-05 19:29:43 +00:00
AutoUpgrade.h Rename loop unrolling and loop vectorizer metadata to have a common prefix. 2014-06-25 15:41:00 +00:00
BasicBlock.h Fix some obvious Doxygen comment bugs. 2014-05-06 05:05:59 +00:00
CallingConv.h Revert "[ms-cxxabi] Add a new calling convention that swaps 'this' and 'sret'" 2014-05-09 22:56:42 +00:00
CallSite.h Improve 'tail' call marking in TRE. A bootstrap of clang goes from 375k calls marked tail in the IR to 470k, however this improvement does not carry into an improvement of the call/jmp ratio on x86. The most common pattern is a tail call + br to a block with nothing but a 'ret'. 2014-05-05 23:59:03 +00:00
