I tried to pay attention to what was actually being tested so, e.g. when I
test was just using a vec as a boxed thing, I converted to boxed ints, etc.
Haven't converted the macro tests yet. Not sure what to do there.
The resulting code is strange, but perhaps someone else can
fix it. The obvious things, like returning body_res, all resulted
in completely incomprehensible LLVM errors.
Closes#814
trans was failing with a bounds check error because the caller
was using the declared type (an out-of-scope ty param) and not
the actual type in a list of argument types to zero.
Closes#811
This reverts commit ea81c03960264bf590cd99ed2b662243e3db7a7c.
Changed the case in trans_if where the conditional is _|_ - typed
but the block is terminated to return the result of the cond,
instead of nil.
This passes "make check" with optimization disabled as well as
enabled.
While it is still technically possible to test stage 0, it is not part of any
of the main testing rules and maintaining xfail-stage0 is a chore. Nobody
should worry about how tests fare in stage0.
This was at least partially responsible for Issue 777.
The only solution I can think of is for trans to just not generate
code for a comparison if one or both sides has type _|_. Since
that means evaluating that subexpression diverges, it should be ok
to never do the comparison. Actually generating code for the
comparison would trip an LLVM assertion failure.
An expression like:
foo(1, fail, 2)
was failing to parse, because the parser was interpreting the comma
as the start of an expression that was an argument to fail, rather
than recognizing that the fail here has no arguments
Fixed this by using can_begin_expr to determine whether the next
token after a fail token suggests that this is a nullary fail or a
unary fail.
In addition, when translating calls, check before translating each
argument that the block still isn't terminated. This has the effect
that if an argument list includes fail, the back-end won't keep trying
to generate code for successive arguments and trip the !*terminated
assertion.
