Elena Demikhovsky acc5c9e83e AVX-512: store and truncstore for i1 values 
llvm-svn: 206897
 2014-04-22 14:13:10 +00:00
Robert Khasanov 189e7fdcfb [AVX512] Implemented integer conversions up/down with masking. 
Added encoding tests.

Filipe Cabecinhas 20352216fb Rename X86insrtps to the proper instruction name. 
Summary:
The INSERTPS pattern fragment was called insrtps (mising 'e'), which
would make it harder to grep for the patterns related to this instruction.
Renaming it to use the proper instruction name.

Craig Topper 5ccb61781f Add an x86 prefix encoding for instructions that would decode to a different instruction with 0xf2/f3/66 were in front of them, but don't themselves have a prefix. For now this doesn't change any bbehavior, but plan to use it to fix some bugs in the disassembler.

Craig Topper ae11aed9d7 Separate the concept of 16-bit/32-bit operand size controlled by 0x66 prefix and the current mode from the concept of SSE instructions using 0x66 prefix as part of their encoding without being affected by the mode. 
This should allow SSE instructions to be encoded correctly in 16-bit mode which r198586 probably broke.

I moved a test from avx512-vbroadcast-crash.ll to avx512-vbroadcast.ll
I defined HasAVX512 predicate as AssemblerPredicate. It means that you should invoke llvm-mc with "-mcpu=knl" to get encoding for AVX-512 instructions. I need this to let AsmMatcher to set different encoding for AVX and AVX-512 instructions that have the same mnemonic and operands (all scalar instructions).

llvm-svn: 193156
 2013-10-22 09:19:28 +00:00
Lang Hames 2783993fca X86 vector element shift-by-immediate instructions take i8 immediates. Make 
the instruction defenitions and ISEL reflect this.

Prior to this patch these instructions took an i32i8imm, and the high bits were
dropped during encoding. This led to incorrect behavior for shifts by
immediates higher than 255. This patch fixes that issue by detecting large
immediate shifts and returning constant zero (for logical shifts) or capping
the shift amount at an encodable value (for arithmetic shifts).

Fixes <rdar://problem/14968098>
