parse_arguments: CannotCache(multiple input files) using /fp:fast with MSVC

[Be-ing]

I am struggling to get sccache working with MSVC using CMake. Maybe there is something already in the CMake project that is messing up sccache. sccache -s shows that every call is noncacheable. The server debug logs show:

Reading #278 (comment) I tried replacing /Zi with /Z7 but that didn't help.

That haunts me too.

No response at all in 10 days? I was hoping sccache would be the one compiler cache that supports MSVC and is still maintained.

[Be-ing]

I found the culprit. Sccache works without using the /fp:fast option. Unfortunately I doubt removing this is acceptable for realtime audio...

[Be-ing]

@garyzyg I suspect your issue is the stray UNICODE argument. You probably want /utf-8 instead.

[Be-ing]

fp is incorrectly treated as a Separated argument but it is really Concatenated. Fix is in #962.

[garyzyg]

@garyzyg I suspect your issue is the stray UNICODE argument. You probably want /utf-8 instead.

@Be-ing sccache cached the result after I removed "/O1ib2s". My case looks different from yours.

[Be-ing]

I don't think there is any /O1ib2s option for MSVC? That would explain why sccache treated it as an extra input file instead of a compiler option.

[garyzyg]

Actually MSVC in WDK 7600.16385.1 accepted this.

Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 15.00.30729.207 for 80x86

EDK2 used it widely.

I think I was hit by this. I solved the issue for myself by downgrading to 0.2.12. The only thing to take care with it is to avoid having spaces after -D
