Although I understand what is the difference between dg-do compile and
dg-do assemble, I have noticed that there are many testcases that use
either dg-compile or dg-do assemble and do nothing with the output.
Thus, I would like to know:
Is it faster {dg-do compile} or {dg-do assemble}?
Our assembler is in the 1-2% range for compile times. So, using the
right one might speed things up 1-2%, if we didn't test on a 2-4
processor box, but we do, so, we don't care. On a 1 processor box,
it is so marginal as to almost not worry about it, though, I'd tend
to pick the right one for tests I author.
Is it appropriate to always use the faster one if the testcase just
checks for the presence/absence of warnings and errors?
Yes, it is appropriate to use the right one. As for which one is
right, the one that FAILs when the compiler has the bug and PASSes
when the compiler has been fixed is a good first order
approximation. Beyond that, if assemble is enough to do that, you
can use it. Some testcases will need compile to elicit a FAIL. It
is natural that some people will tend to use compile instead of
assemble occasionally, when assemble would have worked, don't worry
about it, it is healthy to have a mix.
