; This test checks to ensure that if a DWARF v5 and DWARF v4 object file is used to
; generate a dsym, dsymutil correctly outputs the debug information, by keeping
; the DWARF v5 and DWARF v4 debug info distinct, and that all the section headers
; have the correct format.
; 1.o was produced with the source file:
; a.cpp
; __attribute__((section("1,__text_foo"))) void foo() {}
;
; int foo2(int a) {
; return a+5;
; }
; int main () {
; return 1;
; }
; clang -g -c -O1 a.cpp -Xclang -gdwarf-5 -o 1.o
; 2.o was produced with the following source file:
; b.cpp
; __attribute__((section("1,__text_foo2"))) void foo2() {}
;
; int bar(int x) {
; int y = x + 2;
; return y;
; }
; clang -g -c -O1 b.cpp -gdwarf-4 -o 2.o
