This mostly involved futzing around with some of the less intuitive
parts of Unix's named-pipes behavior.
This is a bit important since the tests can quickly generate several
gigabytes of trace output.
These have no real purpose other than slowing down the simulation
for inspection/fun.
Note this did reveal an issue in pretty_asserts.py which was clobbering
feature macros. Added explicit, and maybe a bit hacky, #undef _FEATURE_H
to avoid this.
- Renamed explode_asserts.py -> pretty_asserts.py, this name is
hopefully a bit more descriptive
- Small cleanup of the parser rules
- Added recognization of memcmp/strcmp => 0 statements and generate
the relevant memory inspecting assert messages
I attempted to fix the incorrect column numbers for the generated
asserts, but unfortunately this didn't go anywhere and I don't think
it's actually possible.
There is no column control analogous to the #line directive. I thought
you might be able to intermix #line directives to put arguments at the
right column like so:
assert(a == b);
__PRETTY_ASSERT_INT_EQ(
#line 1
a,
#line 1
b);
But this doesn't work as preprocessor directives are not allowed in
macros arguments in standard C. Unfortunately this is probably not
possible to fix without better support in the language.
