[9fans] C compiler error?
New features in Go require a new function in the reflect.c module (src/cmd/gc/reflect.c). The C compiler (8c, in this case) reports an error which does not seem to apply: 8c -I/go/include -I/go/386/include -FTVw ../gc/reflect.c ../gc/reflect.c:987 switch expression must be integer This is a bit of a stumbling block. I'm hoping there's someone on this mailing list that can address this problem quicker than it would be possible for me. More details off line. ++L

Erik, are you looking at the tip? IIRC the webpage points to a stable version not the tip.

Lucio De Re lu...@proxima.alt.za once said: New features in Go require a new function in the reflect.c module (src/cmd/gc/reflect.c).

If you we're using 6c you could have a vlong in a switch expression. I sent out a CL for this: https://codereview.appspot.com/5486049/ Anthony

Re: [9fans] C compiler error?
it's reasonable to use any integer type in a switch, although the compilers don't currently support it. it's compatible with the standard, which allows any integer type. i'd cancel the change request and work round it (add a cast) until the compilers can be changed to support it.

What is the expected status? Is Anthony's CL to be abandoned in favour of the change to the Plan 9 C compiler (give or take the other nit of a static definition)? I don't have a problem with minor unofficial changes to the Plan 9 distribution, but others may object. Lucio. ---End Message---

I don't have a problem with minor unofficial changes to the Plan 9 distribution, but others may object. Since you sent this publicly, I will reply publicly. We're not going to change the Go code to avoid switches on 64-bit numbers, which are increasingly common. I assume that Anthony will take care of submitting the patch through the usual channels and getting it applied. Russ
