[LLVMdev] FP Stack overflow with inline asm
...bbered
Will result in the same output for gcc-4.2 and clang:
fldt 0.84711
## InlineAsm Start
fistl -4(%ebp)
## InlineAsm End
This code seems fine, of course it doesn't work but is exactly what was requested.
The issue can we worked around by using the following asm statement:
__asm__("fistpl %0": "=m"(r) : "t"(v) : "st");
which actively pops the value from the stack but i really would like to understand (and fix) the root of the problem and not tamper some band aid over it.
I'm happy to file a bug if someone can confirm that my inline asm unders...

[patch 0/4] Clean up asm/bugs.h, identify_cpu() and update COMPAT_VDSO
Hi Andi,
Four patches:
- clean up asm/bugs.h, by moving all the C code into its own C file
- split identify_cpu() into boot and secondary variants, so that
boot-time setup functions can be marked __init
- repost of the COMPAT_VDSO patches with a bit more robustness from
unknown DT_tags, and functions marked __init, since all this is
boot-time only setup.
Thanks,
J
