- ! bcc 386 floating point routines (version 2) -- Fpulld
- ! authors: Timothy Murphy (tim@maths.tcd.ie), Bruce Evans
- #include "fplib.h"
- ! Pop double from stack and store at address [ebx]
- .globl Fpulld
- .align ALIGNMENT
- Fpulld:
- pop ecx
- pop dword D_LOW[ebx]
- pop dword D_HIGH[ebx]
- jmp ecx ! return
- ! This popping method is much slower on 486's because popping to memory
- ! takes 5+ while moving twice takes 2 and the return address doesn't
- ! have to be moved. However, popping is a little faster on a non-cached
- ! 386/20 with static column RAM although the memory access pattern is
- ! better for a double-width move than for popping. What about a cached 386?
