Hi all,
*package main*
*func main() {*
* foo()*
*}*
*func foo() {*
* a := 5*
* _ = a*
* foo()*
*}*
I have generated the below llvm ir using the command `./bin/llvm-goc -S
test.go -dump-ir`. I expected there are some llvm intrinsics that have been
used to handle stack overflow. But it is not there. How does gollvm handle
stackoverflow?
*define void @main.main(i8* nest %nest.0) #0 !dbg !14 {*
*entry:*
* call void @main.foo(i8* nest undef), !dbg !15*
* ret void*
*}*
*define void @main.foo(i8* nest %nest.1) #0 !dbg !16 {*
*entry:*
* %a = alloca i64, align 8*
* %0 = bitcast i64* %a to i8**
* call void @llvm.lifetime.start.p0i8(i64 8, i8* %0)*
* store i64 5, i64* %a, align 8*
* call void @llvm.dbg.declare(metadata i64* %a, metadata !17, metadata
!DIExpression()), !dbg !20*
* %a.ld.0 = load i64, i64* %a, align 8, !dbg !21*
* call void @main.foo(i8* nest undef), !dbg !22*
* %1 = bitcast i64* %a to i8**
* call void @llvm.lifetime.end.p0i8(i64 8, i8* %1)*
* ret void*
*}*
