development branch:
- Preliminary exception handling per
ECMA proposal; try, multiple
catchblocks, and finally. Catchblocks
are of the form catch (v) or
catch(v:<guard>), where guard is an
optional boolean expression that is
evaluated to determine whether the
exception is to be caught by that block.
- ECMA-proposed 'in' operator; "'foo' in
o" or "4 in o" asks if o has property
foo or element 4.
- Added a new set of defines in
jsconfig.h for js 1.4
features-in-progress. (in, instanceof,
exception handling.) Default build
version is now 1.4. Fixed a few
conditional features that had become
broken.
- Progress towards porting to FreeBSD
and Alpha; casts of NaN and friends to
int are a little more localized. Not
there yet...
- New config files to compile on more
OSes; various fixes to improve
portability.
- Revise exception handling runtime info (now called trynotes a la srcnotes)
for more efficient loop control under JSOP_THROW. Avoid all uses of catch
and throw while at it, to make C++ lusers happy.
- Combine JSStackFrame.exception with rval, and rename
JSStackFrame.exceptPending to be ...throwing.
- Optimize JS_TypeOfValue a bit.
- Name, control flow, whitespace, etc. cleanup.
