93aabf1533 Fixed bug #77275 
Instead of juggling with this problem during literal compaction,
make sure that we always initialize Z_EXTRA for literals, which
seems like the more robust solution.

b9431ef4d5 Don't optimize function if inference failed 
This was respected only for the single-function optimizations, not
in func-info mode.

30156d588c Fixed bug #63217 
Don't automatically convert literal string keys to integers on
array access, as we may be dealing with an ArrayAccess object,
rather than a plain array.

b0af9ac733 Avoid live range references in opcodes 
Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely codepath (in particular, it requires a loop variable with
a throwing destructor), saving the runtime lookup of the live range
is not worth the extra complexity this adds everywhere else.

3a794d39f0 Avoid repeatable ARG_SHOULD_BE_SENT_BY_REF() checks in FETCH_*FUNC_ARG and following SEND_VAR_EX. Perform the check once in a new CHECK_FUNC_ARG opcode and reuse in the following FETCH_*FUNC_ARG and SEND_FUNC_ARG (SEND_VAR_EX replacement). 2018-02-05 19:40:06 +03:00
