The documentation for __RTL tests (see "(gccint) RTL Tests" info node) has the
following snippet.
```
The parser expects the RTL body to be in the format emitted by this
dumping function:
DEBUG_FUNCTION void
print_rtx_function (FILE *outfile, function *fn, bool compact);
when "compact" is true. So you can capture RTL in the correct format
from the debugger using:
(gdb) print_rtx_function (stderr, cfun, true);
and copy and paste the output into the body of the C function.
```
Since r264944 print_rtx_function prints column number information, which the
__RTL function parsing does not handle.
This patch handles column number information optionally, so pre-existing __RTL
functions still work, and the above documentation quote still holds.
Note: If people would prefer to require column information I could make a
slightly neater code and update existing tests.
I guess this would be OK since the intended use for __RTL functions is in these
testcases so there is no worry about other existing code.
bootstrapped and regtested on aarch64
bootstrapped and regtested on x86_64
Ok for trunk?
Cheers,
