Summary: ICE converting between double and long double with -
msoft-float
Product: gcc
Version: 3.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: taylor at candd dot org
CC: gcc-bugs at gcc dot gnu dot org
GCC target triplet: i686-pc-linux-gnu
The following simple function (extracted from libstdc++-v3/libmath/stubs.c)
will get an internal compiler error.
extern double atan2(double, double);
long double
atan2l(long double x, long double y)
{
return atan2((double) x, (double) y);
}
The ICE occurs with x86 native on GNU/Linux with GCC 3.3.1 when invoked with
-msoft-float. It does not ICE with GCC 2.95.3. I haven't yet tried the HEAD
of the CVS trunk.

>From Phil's regression hunter: Search converges between 2001-06-10-trunk (#23) and 2001-06-
17-trunk (#24). Note this was hard to use Phil's regression hunter because it does not fail for -
arch=i386.

* i386.c (x86_accumulate_outgoing_args, x86_prologue_using_move,
x86_epilogue_using_move): New global variables.
(override_options): Enable ACCUMULATE_OUTGOING_ARGS if preferred.
(ix86_emit_save_regs_using_mov): New static function.
(ix86_expand_prologue, ix86_expand_epilogue): Use moves if preferred.
* i386.h (MASK_MMX, MASK_SSE, MASK_SSE2, MASK_128BIT_LONG_DOUBLE,
MASK_MIX_SSE_I387): Renumber.
(MASK_NO_ACCUMULATE_OUTGOING_ARGS): New.
(x86_accumulate_outgoing_args, x86_prologue_using_move,
x86_epilogue_using_move): Declare.
(TARGET_PROLOGUE_USING_MOVE, TARGET_EPILOGUE_USING_MOVE): New.
The regression hunt took place on i686-pc-linux-gnu using the submitter's
test case compiled with -msoft-float with cc1.
