No ICE if change pentium-mmx to pentium2.

[Bug target/21102] New: ICE: in immed_double_const, on SSE2 intrinsics

ICE on gcc 4.0.0rc2, but both 3.3.5 and 3.4.3 work.

$ /usr/local/gcc-4.0/bin/g++ -c -O -msse2 4.cpp
4.cpp: In function 'void f()':
4.cpp:10: internal compiler error: in immed_double_const, at emit-rtl.c:467

Here is the source:

  __m128i A;
  A = _mm_add_epi8(A,A);
  A = _mm_andnot_si128(A,A);

[Bug inline-asm/18074] New: SSE2 intrinsics generates wrong code

2004-10-20 Thread jochang at gmail dot com 
The command line: gcc -O2 -msse2 -S 2.c
The code:
#include 
int f(__m128i x, __m128i y)
{
  __m128i m[1];
  m[0] = _mm_add_epi16(x, y);
  return *(int*)(&m[0]);
}
int g(__m128i x, __m128i y)
{
  __m128i m[2];
  m[0] = _mm_add_epi16(x, y);
  return *(int*)(&m[0]);
}

The compiler generates correct code for f(),
but for g() the add operation (paddw) disappears.
Happens on GCC 3.3.4 and 3.4.2

[Bug target/18779] New: SSE2 intrinsics cause segmentation fault and internal compiler error

2004-12-02 Thread jochang at gmail dot com 
Command line: gcc -msse2 -O main.c

(1) The generated executable causes segmentation fault while running. It looks
like some alignment problem.

(2) If test1 and test2 are called directly from main(), not through test3, the
problem disappears.

(3) If the line "t2 = coeffs" in test1 is commented out, ICE happens:
main.c: In function `test1':
main.c:33: internal compiler error: in immed_double_const, at emit-rtl.c:481

The test case

The problem happens on 3.4.2 and 3.4.3, but not on 3.3.4.
