[Bug c/13292] New: -msoft-float seems to corrupt builtin defines

[john at atrove dot com]

Whilst compiling my application I noticed some of the buildin defines where 
not as expected.  Some basic tests showed that the -msoft-float flag seemed to 
be changing the builtin defines.  See results below

Compiler versions

$ m68k-rtems-gcc -v -c -m68040 -save-temps test.c

int ismc68030;
#endif

#ifdef mc68040

#endif

#ifdef mc68060
int ismc68060;
#endif

Results with m68k-rtems-gcc -save-temps -m68040, as expected

$ cat test.040
# 1 "<built-in>"
# 1 "<command line>"

int ismc68000;
# 34 "test.c"
int ismc68040;

Results with m68k-rtems-gcc -save-temps -m68040 -msoft-float in error seems to 
define other symbols

$ cat test.040.soft
# 1 "<built-in>"

[Bug target/13292] -msoft-float seems to corrupt builtin defines

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2003-12-04 08:18 -------
Most likely caused by the reorg of m68k.h for the new way of doing builtin defines.

Is this a regression?

Predefines used to work consistently in 3.3.3 with respect
to -msoft-float, so technically it's a regression, although
we had different rules to map -m680[02346]0 to predefines.
