2012-07-18This patch fixes 8 out of 20 unexpected failures in "make check"Preston Gurd
when run on an Intel Atom processor. The failures have arisen due to changes elsewhere in the trunk over the past 8 weeks or so. These failures were not detected by the Atom buildbot because the CPU on the Atom buildbot was not being detected as an Atom CPU. The fix for this problem is in Host.cpp and X86Subtarget.cpp, but shall remain commented out until the current set of Atom test failures are fixed.

2012-07-18The vbroadcast family of instructions has 'fallback patterns' in case where theNadav Rotem
load source operand is used by multiple nodes. The v2i64 broadcast was emulated by shuffling the two lower i32 elements to the upper two. We had a bug in the immediate used for the broadcast. Replacing 0 to 0x44. 0x44 means [01|00|01|00] which corresponds to the correct lane. Patch by Michael Kuperstein. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160430 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18Mips specific inline asm operand modifier 'M':Jack Carter
Print the high order register of a double word register operand. In 32 bit mode, a 64 bit double word integer will be represented by 2 32 bit registers. This modifier causes the high order register to be used in the asm expression. It is useful if you are using doubles in assembler and continue to control register to variable relationships. This patch also fixes a related bug in a previous patch: case 'D': // Second part of a double word register operand case 'L': // Low order register of a double word register operand case 'M': // High order register of a double word register operand I got 'D' and 'M' confused. The second part of a double word operand will only match 'M' for one of the endianesses. I had 'L' and 'D' be the opposite twins when 'L' and 'M' are. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160429 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-18More replacing of target-dependent intrinsics with target-indepdent Joel Jones
intrinsics. The second instruction(s) to be handled are the vector versions of count set bits (ctpop). The changes here are to clang so that it generates a target independent vector ctpop when it sees an ARM dependent vector bits set count. The changes in llvm are to match the target independent vector ctpop and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector pop counts with target-independent ctpops. There are also changes to an existing test case in llvm for ARM vector count instructions and to a test for the bitcode upgrade. <rdar://problem/11892519> There is deliberately no test for the change to clang, as so far as I know, no consensus has been reached regarding how to test neon instructions in clang; q.v. <rdar://problem/8762292> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160410 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-16For something likeEvan Cheng
uint32_t hi(uint64_t res) { uint_32t hi = res >> 32; return !hi; } llvm IR looks like this: define i32 @hi(i64 %res) nounwind uwtable ssp { entry: %lnot = icmp ult i64 %res, 4294967296 %lnot.ext = zext i1 %lnot to i32 ret i32 %lnot.ext } The optimizer has optimize away the right shift and truncate but the resulting constant is too large to fit in the 32-bit immediate field. The resulting x86 code is worse as a result: movabsq $4294967296, %rax ## imm = 0x100000000 cmpq %rax, %rdi sbbl %eax, %eax andl $1, %eax This patch teaches the x86 lowering code to handle ult against a large immediate with trailing zeros. It will issue a right shift and a truncate followed by a comparison against a shifted immediate. shrq $32, %rdi testl %edi, %edi sete %al movzbl %al, %eax It also handles a ugt comparison against a large immediate with trailing bits set. i.e. X > 0x0ffffffff -> (X >> 32) >= 1 rdar://11866926 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160312 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-16Fix a bug in the 3-address conversion of LEA when one of the operands is anNadav Rotem
undef virtual register. The problem is that ProcessImplicitDefs removes the definition of the register and marks all uses as undef. If we lose the undef marker then we get a register which has no def, is not marked as undef. The live interval analysis does not collect information for these virtual registers and we crash in later passes.

2012-07-16This CL changes the function prologue and epilogue emitted on X86 when stack ↵Alexey Samsonov
needs realignment. It is intended to fix PR11468. Old prologue and epilogue looked like this: push %rbp mov %rsp, %rbp and $alignment, %rsp push %r14 push %r15 ... pop %r15 pop %r14 mov %rbp, %rsp pop %rbp The problem was to reference the locations of callee-saved registers in exception handling: locations of callee-saved had to be re-calculated regarding the stack alignment operation. It would take some effort to implement this in LLVM, as currently MachineLocation can only have the form "Register + Offset". Funciton prologue and epilogue are now changed to: push %rbp mov %rsp, %rbp push %14 push %15 and $alignment, %rsp ... lea -$size_of_saved_registers(%rbp), %rsp pop %r15 pop %r14 pop %rbp Reviewed by Chad Rosier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160248 91177308-0d34-0410-b5e6-96231b3b80d8
