When AC_PROG_CC picks GCC, move its selection of CFLAGS
into CPPFLAGS, so that preprocessing will have the same
optimization and debugging flags as compilation.
Arguably, AC_PROG_CC plus AC_PROG_CPP should do that
soemhow, but it's understandable that the autoconf
implementers didn't cover the possibility of
preprocessing that changes with the optimization level.
Closes#945
- Coalesce repeated use of the same predicate.
- Fix scoring of Exact patterns, and scoring generally.
- Use `OrderedAnd` where needed.
- Guarantee that `and` patterns match in order.
- Thread bound variable information properly in GSeq compilation.
- Warn when variables are used non-linearly with `...`
(making this behave properly was not backwards compatible).
Closes#952, which now runs in <1ms and make it a test case.
Also add margin note about `?` patterns and multiple calls.
Before consulting a catalog, etc., check whether a given package name
is currently installed. The new check applies only if a scope is
specified, since scope inference implies the check already.
When `local-require` is used in a non-phase-0 position and it is
`expand`ed (as opposed to compiled directly), then the generated
`#%require` form had the wrong binding phase.
Merge to v6.2
In many use cases the length of the vector is fixed and know,
so we are sure that make-vector will not raise an error and
we can recognize these expressions as omittable and drop
them when the result is ignored.
The result of some procedures is a vector, but they are not omittable
because they may rise an error. With the recent changes of the
predicate reduction these cases are correctly handled.
Adds a sealing and unsealing function to attach (or detach)
seals onto a class via impersonator properties. Since these
properties override, they do not accumulate wrappers.
Calling seal multiple times will still accumulate multiple seal
values inside the property.
A sealed class cannot be instantiated and a subclass may not
add class members that match any of the sealed names in its
sealed parent.
These functions are intended for use by TR's `sealing->/c`
contract, but are parameterized over checking functions and
could be used for other purposes.
An empty string provided to `raco pkg config --set catalogs` would
trigger an error previously. Instead, turn it into a `#f` in the
configuration file, which is replaced by the default search sequence.
The optimizer checks the type of the argument of some unary procedures and
uses the gathered information to replace them by the unsafe version, reduce
predicates and detect type errors. This extends the checks to more procedures
that have no unsafe version and procedures that have more than one argument.
