From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.target/i386/m128-check.h | 166 +++++++++++++++++++++++++++++ 1 file changed, 166 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/m128-check.h (limited to 'gcc/testsuite/gcc.target/i386/m128-check.h') diff --git a/gcc/testsuite/gcc.target/i386/m128-check.h b/gcc/testsuite/gcc.target/i386/m128-check.h new file mode 100644 index 000000000..4e2deecb1 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/m128-check.h @@ -0,0 +1,166 @@ +#include +#include + +#ifdef __SSE2__ +#include + +typedef union +{ + __m128i x; + char a[16]; +} union128i_b; + +typedef union +{ + __m128i x; + unsigned char a[16]; +} union128i_ub; + +typedef union +{ + __m128i x; + short a[8]; +} union128i_w; + +typedef union +{ + __m128i x; + unsigned short a[8]; +} union128i_uw; + +typedef union +{ + __m128i x; + int a[4]; +} union128i_d; + +typedef union +{ + __m128i x; + long long a[2]; +} union128i_q; + +typedef union +{ + __m128d x; + double a[2]; +} union128d; +#endif + +typedef union +{ + __m128 x; + float a[4]; +} union128; + +#ifndef ARRAY_SIZE +#define ARRAY_SIZE(A) (sizeof (A) / sizeof ((A)[0])) +#endif + +#ifdef DEBUG +#define PRINTF printf +#else +#define PRINTF(...) +#endif + +#define CHECK_EXP(UINON_TYPE, VALUE_TYPE, FMT) \ +static int \ +__attribute__((noinline, unused)) \ +check_##UINON_TYPE (UINON_TYPE u, const VALUE_TYPE *v) \ +{ \ + int i; \ + int err = 0; \ + \ + for (i = 0; i < ARRAY_SIZE (u.a); i++) \ + if (u.a[i] != v[i]) \ + { \ + err++; \ + PRINTF ("%i: " FMT " != " FMT "\n", \ + i, v[i], u.a[i]); \ + } \ + return err; \ +} + +#ifdef __SSE2__ +CHECK_EXP (union128i_b, char, "%d") +CHECK_EXP (union128i_ub, unsigned char, "%d") +CHECK_EXP (union128i_w, short, "%d") +CHECK_EXP (union128i_uw, unsigned short, "%d") +CHECK_EXP (union128i_d, int, "0x%x") +CHECK_EXP (union128i_q, long long, "0x%llx") +CHECK_EXP (union128d, double, "%f") +#endif + +CHECK_EXP (union128, float, "%f") + +#define ESP_FLOAT 0.000001 +#define ESP_DOUBLE 0.000001 +#define CHECK_ARRAY(ARRAY, TYPE, FMT) \ +static int \ +__attribute__((noinline, unused)) \ +checkV##ARRAY (const TYPE *v, const TYPE *e, int n) \ +{ \ + int i; \ + int err = 0; \ + \ + for (i = 0; i < n; i++) \ + if (v[i] != e[i]) \ + { \ + err++; \ + PRINTF ("%i: " FMT " != " FMT "\n", \ + i, v[i], e[i]); \ + } \ + return err; \ +} + +CHECK_ARRAY(i, int, "0x%x") +CHECK_ARRAY(l, long long, "0x%llx") + +#define CHECK_FP_ARRAY(ARRAY, TYPE, ESP, FMT) \ +static int \ +__attribute__((noinline, unused)) \ +checkV##ARRAY (const TYPE *v, const TYPE *e, int n) \ +{ \ + int i; \ + int err = 0; \ + \ + for (i = 0; i < n; i++) \ + if (v[i] > (e[i] + (ESP)) || v[i] < (e[i] - (ESP))) \ + if (e[i] != v[i]) \ + { \ + err++; \ + PRINTF ("%i: " FMT " != " FMT "\n", \ + i, v[i], e[i]); \ + } \ + return err; \ +} + +CHECK_FP_ARRAY (d, double, ESP_DOUBLE, "%f") +CHECK_FP_ARRAY (f, float, ESP_FLOAT, "%f") + +#ifdef NEED_IEEE754_FLOAT +union ieee754_float +{ + float d; + struct + { + unsigned long frac : 23; + unsigned exp : 8; + unsigned sign : 1; + } bits __attribute__((packed)); +}; +#endif + +#ifdef NEED_IEEE754_DOUBLE +union ieee754_double +{ + double d; + struct + { + unsigned long frac1 : 32; + unsigned long frac0 : 20; + unsigned exp : 11; + unsigned sign : 1; + } bits __attribute__((packed)); +}; +#endif -- cgit v1.2.3
