[go-nuts] Is Go a single pass compiler?

Hello, In Go functions can be used before they are defined, but as I understand, it's still possible to have a single pass compiler. Thanks -- You received this message because you are subscribed to the Google Groups "golang-nuts" group. To unsubscribe from this group and stop receiving emai

Re: [go-nuts] Is Go a single pass compiler?

Thanks, Ian. I remember reading in some compiler book that languages should be designed for a single pass to reduce compilation speed. Go proves that wrong :) It's amazingly fast, looks like computers are pretty good at traversing AST trees. On Wednesday, February 27, 2019 at 11:50:05 PM UTC+1

[go-nuts] If Go is using libc instead of syscalls on macOS now, why is it not shown via otool -L?

Hello, I read the following from one of the contributors: > On Solaris (and Windows), and more recently in macOS as well we link with libc (or equivalent). > Go used to do raw system calls on macOS, and binaries were occasionally broken by kernel updates. Now Go uses libc on macOS. I just chec

Re: [go-nuts] If Go is using libc instead of syscalls on macOS now, why is it not shown via otool -L?

Indeed, it works with Go 1.12. I have 3 different Go versions, and my aliasing was messed up. Sorry. > No. The Linux kernel, fortunately, supports static linking and provides a stable syscall API. There is no reason to make this change on GNU/Linux. Good to know, thanks. So Linux, BSD, Plan9

Re: [go-nuts] If Go is using libc instead of syscalls on macOS now, why is it not shown via otool -L?

I know that calling C functions via cgo is relatively expensive because of the goroutines, so there must be some optimizations/tricks to make all these libc calls fast. On Saturday, May 4, 2019 at 12:21:27 AM UTC+2, ivan.m...@gmail.com wrote: > > Indeed, it works with Go 1.12. I have 3 different

[go-nuts] Is it possible to use the Go linker to link C object files?

Go linker is amazing. It's the only truly cross platform linker. Is it possible to use it to create binaries from object files compiled with C? For example main.c: int main() { puts("Hello"); return 0; } gcc -c -o main.o main.c go tool link main.o main.o: not package main -- You received t

Thanks very much. This is all very interesting. On Sat, May 4, 2019 at 2:20 AM wrote: > I don't have hard numbers on slowdowns. It will depend a lot on the binary > in question. > At the time I checked the compiler and linker and it did not slow those > down (to the accuracy of our benchmarks).
