[go-nuts] Re: Why does one string concatenation escape, but the other not?

Now, I think the escape analysis message should be "a + a does not escapes", which accurate meaning is "the header part of a + a does not escape". It is impossible for the compiler to determine whether or notthe underlying part of "a + a" will escape to heap. On Wednesday, June 23, 2021 at 12:00:

[go-nuts] Linker command failing for particular go tests involving net/http and time packages

I'm running a go test to test a function that pings to websites, and returns which one gives me the faster response. The test file is called 'hello_test.go'. This is the code for the test hello_test.go Now, this is how my actual function looks like hello.go

I did not use any *go build* command. Sorry if I missed anything. These are the steps I followed. 1. Build gollvm referring to the official documentation. I followed the steps until https://go.googlesource.com/gollvm/#cmakeninja. 2. I was able to see the *llvm-goc *in the bin folder. I export

Re: [go-nuts] Hi all,

Thank you. Do not I need to check out for a special commit? Can I build the gollvm by checking out the latest commits in all dependant repositories(llvm-project, libbacktrace, libgo etc)? Thank you, Kavindu On Thursday, 24 June 2021 at 21:06:28 UTC+5:30 th...@google.com wrote: > This change has

Re: [go-nuts] How to get the executable file from LLVM IR generated by gollvm

Hello, What you're talking about is not something that's currently supported by gollvm. The way that the gollvm driver code is structured, each input file is placed into one of three categories: Go source files, assembly files, and "everything else". Files that fall into the third category are p

Hello, If you go into your LLVM IR dump and look at the place where the function is defined, you'll see a reference to an attribute set, e.g. define void @main.foo(i8* nest %nest.1) #0 !dbg !16 { Here "#0" refers to this attribute set (appearing later in the dump): attributes #0 = { "disable-
