Build Wren for more targets, and run the test suite on both 32 and 64
bit builds.
* Update the build config to test both with and without NAN_TAGGING
defined.
* Updatest `util/test.py` to take the executable suffix as a
parameter. This allows the makefile to control which binaries will be
tested.
Adds a new target to the makefile to be run by travis, this runs the
test suite against all of the configurations it builds.
* Gcc on some 32 bit platforms was complaining about numeric overflows
when -INFINITY was used. Update the logic for converting a double to
a string to not explicitly check against the literal values.
* Make CI builds run the tests on both 64 _and_ 32 bit builds.
* If I limit the number of CPUs on my MBP I can get some of the tests
to time out, I'm imagining that the specs of the Travis Macs means
that the same is happening there too. Updated the test script to
allow an extra few seconds for the test to complete successfully
before killing it.
* Due to slight differences in accuracy in some computations tests were
failing on 32 bit builds. Stop comparing things quite as exactly in
the cases where it is causing issues.
For some reason 12.34 was refusing to compare equal to itself. Bad
show 12.34 :-/. I've also updated the test so it doesn't leak handles
even if the assertions fail.
* Double-cast from `double` to `uint32_t` to prevent undefined
behaviour on overflow of basic integers. This should hopefully
prevent 32 bit test failures on Linux.
* Move to a version of LibUV with a fix for the 32 bit build error on
Travis.
- Rename "size" -> "count" to be consistent with other usage.
- Remove "Slot" from the function names, since that's implicit.
- Make the getListElement() just move the element to another slot. This
matches other APIs where we distinguish accessing a value and
converting it to some specific type.
This PR adds support for retrieving list information from a slot. Rather
than take the whole list, two different methods are provided for
retrieving a) the length of the list, and b) a specific value in the
list.
- wrenEnsureSlots()
Lets you go the foreign slot stack to make room for a temporary work
area.
- wrenSetSlotNewList()
Creates a new empty list and stores it in a slot.
- wrenInsertInList()
Takes a value from one slot and inserts it into the list in another.
Still need more functions like getting elements from a list, removing,
etc. but this at least lets you create, populate, and return lists from
foreign methods.
This turns those functions into general-purpose functions for writing
raw C values into slots on the foreign call stack.
Writing a return just means writing a value to slot 0.
