With the test-case of PR90009 we run into a SIGSEGV in nvptx_neuter_pars, because par->join_insn and par->join_block are NULL. Detect this problem earlier, by adding an assert in nvptx_find_par that asserts that a fork cannot be paired with more than one join.

2019-06-12Replace std::to_string for integers with optimized versionJonathan Wakely9-75/+365
The std::to_chars functions from C++17 can be used to implement std::to_string with much better performance than calling snprintf. Only the __detail::__to_chars_len and __detail::__to_chars_10 functions are needed for to_string, because it always outputs base 10 representations. The return type of __detail::__to_chars_10 should not be declared before C++17, so the function body is extracted into a new function that can be reused by to_string and __detail::__to_chars_10. The existing tests for to_chars rely on to_string to check for correct answers. Now that they use the same code that doesn't actually ensure correctness, so add new tests for std::to_string that compare against printf output. * include/Makefile.am: Add new <bits/charconv.h> header. * include/Makefile.in: Regenerate. * include/bits/basic_string.h (to_string(int), to_string(unsigned)) (to_string(long), to_string(unsigned long), to_string(long long)) (to_string(unsigned long long)): Rewrite to use __to_chars_10_impl. * include/bits/charconv.h: New header.

2019-06-12[arm] Implement usadv16qi and ssadv16qi standard namesPrzemyslaw Wirkus7-0/+101
This patch implements the usadv16qi and ssadv16qi standard names for arm. The V16QImode variant is important as it is the most commonly used pattern: reducing vectors of bytes into an int. The midend expects the optab to compute the absolute differences of operands 1 and 2 and reduce them while widening along the way up to SImode. So the inputs are V16QImode and the output is V4SImode. I've based my solution on Aarch64 usadv16qi and ssadv16qi standard names current implementation (r260437). This solution emits below sequence of instructions: VABDL.u8 tmp, op1, op2 # op1, op2 lowpart VABAL.u8 tmp, op1, op2 # op1, op2 highpart VPADAL.u16 op3, tmp So, for the code: $ arm-none-linux-gnueabihf-gcc -S -O3 -march=armv8-a+simd -mfpu=auto -mfloat-abi=hard usadv16qi.c -dp #define N 1024 unsigned char pix1[N]; unsigned char pix2[N]; int foo (void) { int i_sum = 0; int i; for (i = 0; i < N; i++) i_sum += __builtin_abs (pix1[i] - pix2[i]); return i_sum; } we now generate on arm: foo: movw r3, #:lower16:pix2 @ 57 [c=4 l=4] *arm_movsi_vfp/3 movt r3, #:upper16:pix2 @ 58 [c=4 l=4] *arm_movt/0 vmov.i32 q9, #0 @ v4si @ 3 [c=4 l=4] *neon_movv4si/2 movw r2, #:lower16:pix1 @ 59 [c=4 l=4] *arm_movsi_vfp/3 movt r2, #:upper16:pix1 @ 60 [c=4 l=4] *arm_movt/0 add r1, r3, #1024 @ 8 [c=4 l=4] *arm_addsi3/4 .L2: vld1.8 {q11}, [r3]! @ 11 [c=8 l=4] *movmisalignv16qi_neon_load vld1.8 {q10}, [r2]! @ 10 [c=8 l=4] *movmisalignv16qi_neon_load cmp r1, r3 @ 21 [c=4 l=4] *arm_cmpsi_insn/2 vabdl.u8 q8, d20, d22 @ 12 [c=8 l=4] neon_vabdluv8qi vabal.u8 q8, d21, d23 @ 15 [c=88 l=4] neon_vabaluv8qi vpadal.u16 q9, q8 @ 16 [c=8 l=4] neon_vpadaluv8hi bne .L2 @ 22 [c=16 l=4] arm_cond_branch vadd.i32 d18, d18, d19 @ 24 [c=120 l=4] quad_halves_plusv4si vpadd.i32 d18, d18, d18 @ 25 [c=8 l=4] neon_vpadd_internalv2si vmov.32 r0, d18[0] @ 30 [c=12 l=4] vec_extractv2sisi/1 instead of: foo: @ args = 0, pretend = 0, frame = 0 @ frame_needed = 0, uses_anonymous_args = 0 @ link register save eliminated. movw r3, #:lower16:pix1 movt r3, #:upper16:pix1 vmov.i32 q9, #0 @ v4si movw r2, #:lower16:pix2 movt r2, #:upper16:pix2 add r1, r3, #1024 .L2: vld1.8 {q8}, [r3]! vld1.8 {q11}, [r2]! vmovl.u8 q10, d16 cmp r1, r3 vmovl.u8 q8, d17 vmovl.u8 q12, d22 vmovl.u8 q11, d23 vsub.i16 q10, q10, q12 vsub.i16 q8, q8, q11 vabs.s16 q10, q10 vabs.s16 q8, q8 vaddw.s16 q9, q9, d20 vaddw.s16 q9, q9, d21 vaddw.s16 q9, q9, d16 vaddw.s16 q9, q9, d17 bne .L2 vadd.i32 d18, d18, d19 vpadd.i32 d18, d18, d18 vmov.32 r0, d18[0] 2019-06-12 Przemyslaw Wirkus <przemyslaw.wirkus@arm.com> * config/arm/iterators.md (VABAL): New int iterator. * config/arm/neon.md (<sup>sadv16qi): New define_expand. * config/arm/unspecs.md ("unspec"): Define UNSPEC_VABAL_S, UNSPEC_VABAL_U values. * gcc.target/arm/ssadv16qi.c: New test. * gcc.target/arm/usadv16qi.c: Likewise.

For this to work, Function::build needs to be adjusted so that Heap_expression::do_get_backend is called when there is a parent block.

2019-06-10compiler: make escape analysis work with imported inlineable functionsIan Lance Taylor3-14/+9
The escape analysis was written before we import inlineable function bodies, and in some places it skipped functions that are not in the local package. Now that there are imported function bodies, make the escape analysis work with them. Note that it is necessary for the escape analysis to run on imported function bodies, even if they are already tagged. The tags only have the information of the parameters (receiver, results), but not the internal nodes, e.g. local variables. We still need to do the analysis to get all the information. (In the future maybe we could export/import escape info for internal nodes also, then we don't need to redo the analysis.) Also add assertions to ensure that if we analyze the same function in multiple places, they'd better agree with each other.

This reproduces the original ICE fixed by r178857 (tested at r178852 and r178860), without depending on a libstdc++ header that keeps changing. The number of errors differs between C++14 and C++17 modes, so the fixed test uses dg-excess-errors to match any number of them. The precise errors aren't what's being tested for here anyway, the point of the test is to verify the ICE in PR 50391 is fixed.
