gen.c assumes "sizeof(float) == sizeof(long)"

Hmm..., what's the `correct' way to do cast the bitpattern
of a float into a long?

float f;
long l = *(long *)(&f);
---
float f;
long l = 0;
memcpy(&l, &f, sizeof( float ) );
---
have two unions, one { double; long } and the other { float,
long } and select the correct one based on sizeof( double )
== sizeof( long ) vs. sizeof( float ) == sizeof( long ), and
emit an error if neither holds?

Can you verify the result is correct if the assertion is
simply removed? I cannot due to lack of x86_64 machines ;-)

I'd recommend to include stdint.h and use uint32_t instead
of unsigned long.

Fixed using Maarten's hint in SDCC r4182.

Ok, so I cut myself here. Visual C, which I happen to use,
does not have the stdint.h header file. Not for VC6 nor
VC7 nor VC8. Luckily someone already implemented a small
open source version of it:

There are probably more out there.

The "official" target-types are:
"TYPE_WORD", "TYPE_UWORD", "TYPE_DWORD" and "TYPE_UDWORD" for
"int", "unsigned int", "long" and "unsigned long". See
"specifier" in SDCCsymt.h

These types are evaluated by 'configure' and stored in
sdccconf.h (there's a sdcc_vc_in.h for VC).

May be aopLiteral() or aopLiteralLong() in SDCCglue.c is
doning what you're looking for.

HTH!

Raphael,

Bernhard is right. Why don't you use aopLiteral()?
Please have a look at the attached patch.

Maarten

Remove bitpatternFromVal, use aopLiteral
