gcc-10.0.0-alpha20191027 snapshot (r277495) ICEs when compiling the following
testcase reduced from gcc/testsuite/gcc.target/i386/sse-23.c (many more
testcases also ICE similarly) w/ -masm=intel:
typedef double vz __attribute__ ((__vector_size__ (16)));
int
v2 (vz pv, vz bc)
{
return __builtin_ia32_ucomisdeq (pv, bc);
}
% x86_64-unknown-linux-gnu-gcc-10.0.0-alpha20191027 -masm=intel -c k467o9dg.c
during RTL pass: final
k467o9dg.c: In function 'v2':
k467o9dg.c:7:1: internal compiler error: output_operand: invalid %-code
