segv inside loop on x86_64
...rowing a segv on x86_64 linux using llvm 3.7.
I cant see what is wrong unless its an alignment problem causing stack
corruption. Its a simple naive absolute value calculation inside a loop
which crashes after about 500000 iterations.
Here is the IR.
; Function Attrs: nounwind uwtable
define void @Main__TestProb() #0 {
entry:
%i = alloca i64, align 8
%j = alloca i64, align 8
store i64 0, i64* %j, align 8
store i64 1, i64* %i, align 8
br label %label_1
label_1: ; preds = %label_2, %entry
%v.87 = load i64, i64* %i, align 8
%abs_icmp = icmp slt i64 %v.87...
