2019-06-13Darwin, testsuite - Adjust two tests that fail on newer OS versions.Iain Sandoe3-2/+7
Newer OS versions (10.14+) do not provide some of the CRTs that are used for older ones (e.g. 10.5), and thus link tests that specify targeting such a revision fail. We retain the testing of the correct defined OS version number but switch to compile-only testing for these two tests. 2019-06-13 Iain Sandoe <iain@sandoe.co.uk> * gcc.dg/darwin-minversion-1.c: Use compile rather than link/run. * gcc.dg/darwin-minversion-2.c: Likewise.

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.
