Hello!
2015-05-13 Uros Bizjak <ubizjak@gmail.com>
* config/alpha/alpha.c (alpha_emit_set_long_const): Remove c1 argument.
(alpha_extract_integer): Redeclare as static HOST_WIDE_INT.
Remove *p0 and *p1 arguments. Rewrite function.
(alpha_legitimate_constant_p): Update call to alpha_extract_integer.
(alpha_split_const_mov): Update calls to alpha_extract_integer and
alpha_emit_set_long_const.
(alpha_expand_epilogue): Update calls to alpha_emit_set_long_const.
(alpha_output_mi_thunk_osf): Ditto.
* config/alpha/alpha.md (movti): Do not check operands[1]
for CONST_DOUBLE.
Tested on alpha-linux-gnu and committed to mainline SVN.
Uros.

Doesn't this now allow CONST_WIDE_INT that are in fact wider than 64 bits?
Which I can't imagine being legitimate...

Indeed. I will look into it in a follow-up patch. There are probably
some more checks for CONST_DOUBLE, I'll look into this later.

I did check this part with:
--cut here--
__int128 a;
void test (void)
{
a = ((__int128) 7 << 100) + ((__int128) 1 << 30);
}
--cut here--
and generated code was identical to unpatched compiler:
ldah $1,16384($31)
lda $2,a
stq $1,0($2)
lda $1,7($31)
sll $1,36,$1
stq $1,8($2)
ret $31,($26),1
However, this works only for TARGET_BUILD_CONSTANTS. This is a
preexisting bug, it looks that we want:

The only part that actually processes CONST_WIDE_INT is
alpha_legitimate_constant and movti expander. The latter immediately
splits any TImode CONST_WIDE_INTs.

Indeed. Also probably worth cleaning up is using CONST_SCALAR_INT_P, where
both CONST_INT and CONST_WIDE_INT are allowed.

I will do this in the last patch, when all uses of CONST_WIDE_INT and
CONST_DOUBLE are reviewed.
For now, I have prepared following patch that cleans
alpha_extract_integer and callers. Please also note that
alpha_legitimate_constant_p now checks full 128 bit constant.
2015-05-14 Uros Bizjak <ubizjak@gmail.com>
* config/alpha/alpha.c (alpha_extract_integer): Do not handle
CONST_WIDE_INT and CONST_DOUBLE. Assert CONST_INT_P (x).
(alpha_legitimate_constant_p) <case CONST_WIDE_INT>: Check high and
low part of the constant using alpha_emit_set_const_1.
(alpha_expand_mov): Do not handle CONST_WIDE_INT and CONST_DOUBLE.
The patch passes bootstrap on alphaev68-linux-gnu, regression test is
in progress.
OK if regtest passes?
Uros.
