| ; Ported from X86 test to cover 2-byte address size case |
| |
| ; Generated from the following source. f4 is used to put a hole in the CU |
| ; ranges while keeping f2 and f4 in the same section (as opposed to |
| ; -ffunction-sections, which would produce CU ranges, but each function would |
| ; be in a different section, so unable to share addresses). The call to f1 at |
| ; the start of f3 ensures the range for the inlined subroutine doesn't share |
| ; the starting address with f3 (so it can be improved by using a rnglist to |
| ; allow it to share an address it wouldn't already be sharing). |
| |
| ; Without f6 being in another section, technically we could use a non-zero CU |
| ; low_pc that could act as a base address for all the addresses in the CU & avoid |
| ; the need for these forced rnglists - we don't do that currently, but f6 ensures |
| ; that this test will remain meaningful even if that improvement is made in the |
| ; future. (implementing that would require detecting that all the addresses in |
| ; the CU ranges are in the same section, then picking the lowest such address as |
| ; the base address to make all other addresses relative to) |
| |
| ; IR from the following, compiled with: |
| ; $ clang -g -c -gdwarf-5 -O1 |
| ; __attribute__((optnone)) void f1() { } |
