[LLVMdev] Call to non-constant memset() being generated where libc is not available
I am compiling something without standard libraries, including no libc.
Somehow, this bitcode is being generated by plain array manipulation code:
%12 = add i8 %11, -19
%tmp35 = icmp sgt i32 %9, 1
%smax36 = select i1 %tmp35, i32 %9, i32 1
call void @llvm.memset.p0i8.i32(i8* getelementptr inbounds ([100 x i8]*
@global_array_char, i32 0, i32 0), i8 %12, i32 %smax36, i32 1, i1 false)
(global_array_char is an array of length 100, which only partially gets
used.)
This gets lowered by LLC to a library...
