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/powerpc/altivec-cell-8.c | 57 +++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 gcc/testsuite/gcc.target/powerpc/altivec-cell-8.c (limited to 'gcc/testsuite/gcc.target/powerpc/altivec-cell-8.c') diff --git a/gcc/testsuite/gcc.target/powerpc/altivec-cell-8.c b/gcc/testsuite/gcc.target/powerpc/altivec-cell-8.c new file mode 100644 index 000000000..dda5eb0c1 --- /dev/null +++ b/gcc/testsuite/gcc.target/powerpc/altivec-cell-8.c @@ -0,0 +1,57 @@ +/* { dg-do run { target { powerpc*-*-* && cell_hw } } } */ +/* { dg-do compile { target { powerpc*-*-* && { ! cell_hw } } } } */ +/* { dg-require-effective-target powerpc_ppu_ok } */ +/* { dg-options "-O2 -maltivec -mabi=altivec -mcpu=cell" } */ +#include +#include + +extern void abort (void); + +typedef short int sint16; +typedef signed char int8; + +int main1(void) __attribute__((noinline)); +int main1(void) +{ + sint16 test_vector[4] = { 1678, -2356, 19246, -17892 }; + int8 test_dst[128] __attribute__(( aligned( 16 ))); + float test_out[4] __attribute__(( aligned( 16 ))); + int p; + + for( p = 0; p < 24; ++p ) + { + memset( test_dst, 0, 128 ); + memcpy( &test_dst[p], test_vector, 8 ); + { + vector float VR, VL, V; + /* load the righthand section of the misaligned vector */ + VR = (vector float) vec_lvrx( 8, &test_dst[p] ); + VL = (vector float) vec_lvlx( 0, &test_dst[p] ); + /* Vector Shift Left Double by Octet Immediate, move the right hand section into the bytes */ + VR = vec_vsldoi( VR, VR, 2 << 2 ); + /* or those two together */ + V = vec_vor( VL, VR ); + /* sign extend */ + V = (vector float) vec_vupkhsh((vector bool short)V ); + /* fixed to float by S16_SHIFT_BITS bits */ + V = (vector float) vec_vcfsx ((vector signed int)V, 5 ); + + vec_stvx( V, 0, &test_out[0] ); + if (test_out[0] != 52.437500) + abort (); + if (test_out[1] != -73.625000) + abort (); + if (test_out[2] != 601.437500) + abort (); + if (test_out[3] != -559.125000) + abort (); + } + } +return 0; +} + + +int main(void) +{ + return main1(); +} -- cgit v1.2.3
