A Helloworld written in C++ is around 75 lines in LLVM IR. However, a Helloworld written in Golang compiled with gollvm is around 900/1000 lines of .ll file. I produced the LLVM IR with instructions from https://go.googlesource.com/gollvm/ I'm using LLVM11, so, older compatible commit of gollvm, not sure newer versions are different.
How can I produce shorter/simplified LLVM IR? Thanks! Cheers, Khanh P/S: An LLVM IR file has a lot of module asm at the start, like: module asm "\09.section \22.go_export\22,\22e\22,@progbits" module asm "\09.ascii \22v3;\\n\22" module asm "\09.ascii \22package \22" module asm "\09.ascii \22main\22" module asm "\09.ascii \22\\n\22" module asm "\09.ascii \22pkgpath \22" module asm "\09.ascii \22main\22" I figure I can delete all the module asm line and my program still runs correctly (I only tested 2 times on simple programs). Is this a legit optimization? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
