As the comment around 7746 says, it's better to use the x87 extended precision
here than SSE. And the generic code doesn't know how to do that. It also regains
the speed lost for the uint64_to_float.c testcase.

of several newly un-defaulted switches. This also helps optimizers
(including LLVM's) recognize that every case is covered, and we should
assume as much.

Right now, this just adds additional entries in match table. The parser does not use them yet.

Fix a crash in AVX2 when trying to broadcast a double into a 128-bit vector. There is no vbroadcastsd xmm, but we do need to support 64-bit integers broadcasted into xmm. Also factor the AVX check into the isVectorBroadcast function. This makes more sense since the AVX2 check was already inside.

Remove hasXMM/hasXMMInt functions. Move callers to hasSSE1/hasSSE2. This is the final piece to remove the AVX hack that disabled SSE.

llvm-svn: 147843

Remove hasSSE*orAVX functions and change all callers to use just hasSSE*. AVX is now an SSE level and no longer disables SSE checks.

Instruction selection priority fixes to remove the XMM/XMMInt/orAVX predicates. Another commit will remove orAVX functions from X86SubTarget.

On Thumb, the displacement computation hardware uses the address of the
current instruction rouned down to a multiple of 4.  Include this
rounding in the UserOffset we compute for each instruction.

When inline asm is present, the instruction alignment may not be known.
Constrain the maximum displacement instead in that case.

This makes it possible for CreateNewWater() and OffsetIsInRange() to
agree about the valid displacements.  When they disagree, infinite
looping happens.

As always, test cases for this stuff are insane.

The pass is prone to looping, and it is better to crash than loop
forever, even in a -Asserts build.

this substraction will result in small negative numbers at worst which
become very large positive numbers on assignment and are thus caught by
the <=4 check on the next line. The >0 check clearly intended to catch
these as negative numbers.

Spotted by inspection, and impossible to trigger given the shift widths
that can be used.

Remove AVX hack in X86Subtarget. AVX/AVX2 are now treated as an SSE level. Predicate functions have been altered to maintain previous names and behavior.

Reorder a bunch of patterns to put the AVX version first thus giving it priority over the SSE version. Another step towards trying to remove the AVX hack that disables SSE from X86Subtarget.

Clean up patterns for MOVNT*. Not sure why there were floating point types on MOVNTPS and MOVNTDQ. And v4i64 was completely missing.

llvm-svn: 147767

Mark MOVNTI as being supported in SSE2 OR AVX mode. This instruction has no AVX equivalent so we should use the SSE version.

llvm-svn: 147766

Move SSE2 logical operations PAND/POR/PXOR/PANDN above SSE1 logical operations ANDPS/ORPS/XORPS/ANDNPS. This fixes a pattern ordering issue that meant that the SSE2 instructions could never be directly selected since the SSE1 patterns would always match first. This is largely moot with the ExeDepsFix pass, but I'm trying to audit for all such ordering issues.

llvm-svn: 147765

Change some places that were checking for AVX OR SSE1/2 to use hasXMM/hasXMMInt instead. Also fix one place that checked SSE3, but accidentally excluded AVX to use hasSSE3orAVX. This is a step towards removing the AVX hack from the X86Subtarget.h

llvm-svn: 147764

Don't disable MMX support when AVX is enabled. Fix predicates for MMX instructions that were added along with SSE instructions to check for AVX in addition to SSE level.

file error checking. Use that to error on an unfinished cfi_startproc.

The error is not nice, but is already better than a segmentation fault.

This eliminates a lot of constant pool entries for -O0 builds of code
with many global variable accesses.

This speeds up -O0 codegen of consumer-typeset by 2x because the
constant island pass no longer has to look at thousands of constant pool
entries.
