| ; Check that call site entries are emitted correctly when using split-dwarf |
| ; together with some form of LTO. |
| |
| ; Original C source: |
| ; |
| ; // cu1.c |
| ; extern void callee(void); |
| ; void caller(void) { |
| ; callee(); |
| ; } |
| ; |
| ; // cu2.c |
| ; __attribute__((optnone)) void callee(void) {} |
| ; |
| ; Steps to reproduce: |
| ; |
| ; (The -O1 here is needed to trigger call site entry emission, as these tags are |
| ; generally not emitted at -O0.) |
