digitalmars.D - FISTTP Instructiion Missing
The asm {} in D is quite handy, but it seems
that the FISTTP instruction is missing. This
one shouln't be too tricky to implement.

The FISTTP instruction doesn't appear in the Intel data sheets. Perhaps you
mean FISTP?

Can be found in the following PDF file: IA-32 Intel® Architecture Software Developer’s Manual Volume 2A: Instruction Set Reference, A-M 2004 FISTTP: Store Integer with Truncation Description: FISTTP converts the value in ST into a signed integer using truncation (chop) as rounding mode, transfers the result to the destination, and pops ST. FISTTP accepts word, short integer, and long integer destinations.The asm {} in D is quite handy, but it seems that the FISTTP instruction is missing.

I believe FISTTP is an SSE3 instruction and not (yet) supported by DMC In article <d2l64r$283h$1 digitaldaemon.com>, Walter says..."Bob W" <nospam aol.com> wrote in message news:d2l0d4$23il$1 digitaldaemon.com...No, as opposed to FISTP, FISTTP bypasses rounding when storing integers, so rounding flags can be left untouched when a truncated result is desired.Hmm, must be a new one.Can be found in the following PDF file: IA-32 Intel® Architecture Software Developer's Manual Volume 2A: Instruction Set Reference, A-M 2004 FISTTP: Store Integer with Truncation Description: FISTTP converts the value in ST into a signed integer using truncation (chop) as rounding mode, transfers the result to the destination, and pops ST.

I found it in the Pentium 4 manuals (it was new for that processor). It's added now to the inline assembler. "pvmoore" <pvmoore_member pathlink.com> wrote in message news:d2mtp5$tpk$1 digitaldaemon.com...I believe FISTTP is an SSE3 instruction and not (yet) supported by DMC

Excellent. Does this mean that the other SSE3 instructions have been added too? ADDSUBPD ADDSUBPS HADDPD HSUBPD HADDPS HSUBPS LDDQU MOVDDUP MOVSHDUP MOVSLDUP MONITOR MWAIT It would be nice to have the full set :) And will they be available to use in DMD 0.120?

The next DMC++ too.
