When trying to eliminate an "sub sp, sp, #N" instruction by folding it into an existing push/pop using dummy registers, we need to account for the fact that this might affect precisely how "fp" gets set in the prologue. We were attempting this, but assuming that *whenever* we performed a fold it would make a difference. This is false, for example, in: push {r4, r7, lr} add fp, sp, #4 vpush {d8} sub sp, sp, #8 we can fold the "sub" into the "vpush", forming "vpush {d7, d8}". However, in that case the "add fp" instruction mustn't change, which we were getting wrong before. Should fix PR18160. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@196769 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, the behavior of IT block generation will be determinated dynamically base on the arch (armv8 vs armv7). This patch adds backend options: -arm-restrict-it and -arm-no-restrict-it. The former one restricts the generation of IT blocks (the same behavior as thumbv8) for both arches. The later one allows the generation of legacy IT block (the same behavior as ARMv7 Thumb2) for both arches. Clang will support -mrestrict-it and -mno-restrict-it, which is compatible with GCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194592 91177308-0d34-0410-b5e6-96231b3b80d8

| * ARM: fold prologue/epilogue sp updates into push/pop for code sizeTim Northover2013-11-084-32/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM prologues usually look like: push {r7, lr} sub sp, sp, #4 If code size is extremely important, this can be optimised to the single instruction: push {r6, r7, lr} where we don't actually care about the contents of r6, but pushing it subtracts 4 from sp as a side effect. This should implement such a conversion, predicated on the "minsize" function attribute (-Oz) since I've yet to find any code it actually makes faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194264 91177308-0d34-0410-b5e6-96231b3b80d8

| * ARM: remove unnecessary state-tracking during frame lowering.Tim Northover2013-11-046-115/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ResolveFrameIndex had what appeared to be a very nasty hack for when the frame-index referred to a callee-saved register. In this case it "adjusted" the offset so that the address was correct if (and only if) the MachineInstr immediately followed the respective push. This "worked" for all forms of GPR & DPR but was only ever used to set the frame pointer itself, and once this was put in a more sensible location the entire state-tracking machinery it relied on became redundant. So I stripped it. The only wrinkle is that "add r7, sp, #0" might theoretically be slower (need an actual ALU slot) compared to "mov r7, sp" so I added a micro-optimisation that also makes emitARMRegUpdate and emitT2RegUpdate also work when NumBytes == 0. No test changes since there shouldn't be any functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194025 91177308-0d34-0410-b5e6-96231b3b80d8

| * Legalize: Improve legalization of long vector extends.Jim Grosbach2013-10-311-55/+0

The end result is the operation often becoming scalarized, with the typical horrible performance. For example, on x86_64, the simple input of: define void @bar(<16 x i8> %a, <16 x i32>* %p) nounwind { %tmp = zext <16 x i8> %a to <16 x i32> store <16 x i32> %tmp, <16 x i32>*%p ret void } Generates: .section __TEXT,__text,regular,pure_instructions .section __TEXT,__const .align 5 LCPI0_0: .long 255 ## 0xff .long 255 ## 0xff .long 255 ## 0xff .long 255 ## 0xff .long 255 ## 0xff .long 255 ## 0xff .long 255 ## 0xff .long 255 ## 0xff .section __TEXT,__text,regular,pure_instructions .globl _bar .align 4, 0x90 _bar: vpunpckhbw %xmm0, %xmm0, %xmm1 vpunpckhwd %xmm0, %xmm1, %xmm2 vpmovzxwd %xmm1, %xmm1 vinsertf128 $1, %xmm2, %ymm1, %ymm1 vmovaps LCPI0_0(%rip), %ymm2 vandps %ymm2, %ymm1, %ymm1 vpmovzxbw %xmm0, %xmm3 vpunpckhwd %xmm0, %xmm3, %xmm3 vpmovzxbd %xmm0, %xmm0 vinsertf128 $1, %xmm3, %ymm0, %ymm0 vandps %ymm2, %ymm0, %ymm0 vmovaps %ymm0, (%rdi) vmovaps %ymm1, 32(%rdi) vzeroupper ret So instead we can check if there are legal types that enable us to split more cleverly when the input vector is already legal such that we don't turn it into an illegal type. If the extend is such that it's more than doubling the size of the input we check if - the number of vector elements is even, - the source type is legal, - the type of a split source is illegal, - the type of an extended (by doubling element size) source is legal, and - the type of that extended source when split is legal. If the conditions are met, instead of just splitting both the destination and the source types, we create an extend that only goes up one "step" (doubling the element width), and the continue legalizing the rest of the operation normally. The result is that this operates as a new, more effecient, termination condition for the loop of "split the operation until the destination type is legal." With this change, the above example now compiles to: _bar: vpxor %xmm1, %xmm1, %xmm1 vpunpcklbw %xmm1, %xmm0, %xmm2 vpunpckhwd %xmm1, %xmm2, %xmm3 vpunpcklwd %xmm1, %xmm2, %xmm2 vinsertf128 $1, %xmm3, %ymm2, %ymm2 vpunpckhbw %xmm1, %xmm0, %xmm0 vpunpckhwd %xmm1, %xmm0, %xmm3 vpunpcklwd %xmm1, %xmm0, %xmm0 vinsertf128 $1, %xmm3, %ymm0, %ymm0 vmovaps %ymm0, 32(%rdi) vmovaps %ymm2, (%rdi) vzeroupper ret This generalizes a custom lowering that was added a while back to the ARM backend. That lowering is no longer necessary, and is removed. The testcases for it, however, provide excellent ARM tests for this change and so remain. rdar://14735100 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193727 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | an MCExpr, in order to avoid writing an encoded zero value in the immediate field. When getUnconditionalBranchTargetOpValue is called with an MCExpr target, we don't know what the final immediate field value should be. We shouldn't explicitly set the immediate field to an encoded zero value as zero is encoded with a non-zero bit pattern. This leads to bits being set that pollute the final immediate value. The nature of the encoding is such that the polluted bits only affect very large immediate values, explaining why this hasn't caused problems earlier.

| * [arm] Implement eabi_attribute, cpu, and fpu directives.Logan Chien2013-10-287-265/+514
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit allows the ARM integrated assembler to parse and assemble the code with .eabi_attribute, .cpu, and .fpu directives. To implement the feature, this commit moves the code from AttrEmitter to ARMTargetStreamers, and several new test cases related to cortex-m4, cortex-r5, and cortex-a15 are added. Besides, this commit also change the Subtarget->isFPOnlySP() to Subtarget->hasD16() to match the usage of .fpu directive. This commit changes the test cases: * Several .eabi_attribute directives in 2010-09-29-mc-asm-header-test.ll are removed because the .fpu directive already cover the functionality. * In the Cortex-A15 test case, the value for Tag_Advanced_SIMD_arch has be changed from 1 to 2, which is more precise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193524 91177308-0d34-0410-b5e6-96231b3b80d8
| * ARM: allow .thumb_func to be separated from symbol definitionTim Northover2013-10-251-17/+18
| | | | | | | | | | | | | | | | | | | | When assembling, a .thumb_func directive is supposed to be applicable to the next symbol definition, even if there are intervening directives. We were racing ahead to try and find it, and this commit should fix the issue.
