2018-01-15compiler: make sure variables captured by defer closure liveIan Lance Taylor2-6/+31
Local variables captured by the deferred closure need to be live until the function finishes, especially when the deferred function runs. In Function::build, for function that has a defer, we wrap the function body in a try block. So the backend sees the local variables only live in the try block, without knowing that they are needed also in the finally block where we invoke the deferred function. Fix this by creating top-level declarations for non-escaping address-taken locals when there is a defer. An example of miscompilation without this CL: func F(fn func()) { didPanic := true defer func() { println(didPanic) }() fn() didPanic = false } With escape analysis turned on, at optimization level -O1 or -O2, the store "didPanic = false" is elided by the backend's optimizer, presumably because it thinks "didPanic" is not live after the store, so the store is useless.

2018-01-15[arm] PR target/83687: Fix invalid combination of VSUB + VABS into VABDKyrylo Tkachov6-45/+61
In this wrong-code bug we combine a VSUB.I8 and a VABS.S8 into a VABD.S8 instruction . This combination is not valid for integer operands because in the VABD instruction the semantics are that the difference is computed in notionally infinite precision and the absolute difference is computed on that, whereas for a VSUB.I8 + VABS.S8 sequence the VSUB operation will perform any wrapping that's needed for the 8-bit signed type before the VABS gets its hands on it. This leads to the wrong-code in the PR where the expected sequence from the intrinsics: VSUB + VABS of two vectors {-100, -100, -100...}, {100, 100, 100...} gives a result of {56, 56, 56...} (-100 - 100) but GCC optimises it into a single VABD of {-100, -100, -100...}, {100, 100, 100...} which produces a result of {200, 200, 200...} The transformation is still valid for floating-point operands, which is why it was added in the first place I believe (r178817) but this patch disables it for integer operands. The HFmode variants though only exist for TARGET_NEON_FP16INST, so this patch adds the appropriate guards to the new mode iterator Bootstrapped and tested on arm-none-linux-gnueabihf.

You can control this behavior for a specific function by using the function attribute indirect_branch. 2 kinds of thunks are geneated. Memory thunk where the function address is at the top of the stack: __x86_indirect_thunk: call L2 L1: pause lfence jmp L1 L2: lea 8(%rsp), %rsp|lea 4(%esp), %esp ret Indirect jmp via memory, "jmp mem", is converted to push memory jmp __x86_indirect_thunk Indirect call via memory, "call mem", is converted to jmp L2 L1: push [mem] jmp __x86_indirect_thunk L2: call L1 Register thunk where the function address is in a register, reg: __x86_indirect_thunk_reg: call L2 L1: pause lfence jmp L1 L2: movq %reg, (%rsp)|movl %reg, (%esp) ret where reg is one of (r|e)ax, (r|e)dx, (r|e)cx, (r|e)bx, (r|e)si, (r|e)di, (r|e)bp, r8, r9, r10, r11, r12, r13, r14 and r15. Indirect jmp via register, "jmp reg", is converted to jmp __x86_indirect_thunk_reg Indirect call via register, "call reg", is converted to call __x86_indirect_thunk_reg gcc/ * config/i386/i386-opts.h (indirect_branch): New. * config/i386/i386-protos.h (ix86_output_indirect_jmp): Likewise. * config/i386/i386.c (ix86_using_red_zone): Disallow red-zone with local indirect jump when converting indirect call and jump.
