FAIL: Why does the output of "llc -march=cpp .." fail to compile with clang 3.8
....
Kind Regards
James
Take a very simple example:
Source code for test.c:
void munge(int *P) {
P[0] = P[1] + P[2];
}
compile with:
clang -c -emit-llvm -o test.bc test.c
test that the .bc output looks sensible
llvm-dis-3.8 test.bc
<snip>
; Function Attrs: nounwind uwtable
define void @_Z5mungePi(i32* %P) #0 {
%1 = alloca i32*, align 8
store i32* %P, i32** %1, align 8
%2 = load i32*, i32** %1, align 8
%3 = getelementptr inbounds i32, i32* %2, i64 1
%4 = load i32, i32* %3, align 4
<snip>
So, that looks good.
compile to -march=cpp
llc-3.8 -march=cpp -o test.cpp test.bc
So,...
