Support parsing a Regexp literal with 'o' option
2019-09-14Revert "Update `%pure-parser` to `%define api.pure` for newer `bison`; fix ↵Yukihiro "Matz" Matsumoto
#4706" The `bison` on MacOS does not support `%define api.pure`. This reverts commit f7c9f1f796d83b9316917681ea068ff648248425.

2019-08-31Skip `nil?` method call in `if` conditionals.Yukihiro "Matz" Matsumoto
Compile `if expr.nil?` to use `OP_JMPNIL` instead of calls.

`strncat()` also needs `'\0'`.

2019-08-17Remove unnecessary `OP_JMPNOT` for `unless` statement.Yukihiro "Matz" Matsumoto
2019-08-16Avoid creating unnecessary empty arrays on splat.Yukihiro "Matz" Matsumoto
But this changes requires `OP_ARYCAT` and `OP_ARYPUSH` to accept `nil` as their first operand. Alternative VMs (e.g. `mruby/c`) that understand mruby bytecode need to be updated.

2019-08-05Use new specifiers/modifiers of `mrb_vfromat()`KOBAYASHI Shuji
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in my environment than before the introduction of new specifiers/modifiers (5116789a) with this change. ------------+-------------------+-------------------+-------- BINARY | BEFORE (5116789a) | AFTER (This PR) | RATIO ------------+-------------------+-------------------+-------- mruby | 593416 bytes | 593208 bytes | -0.04% libmruby.a | 769048 bytes | 767264 bytes | -0.23% ------------+-------------------+-------------------+-------- BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613, so I put it back.

Also fix the misfeature introduced in 23783a4, that ignores newlines between method chains.
2019-07-17Revert #4300KOBAYASHI Shuji
Originally, it was not necessary to change. I made mistake.

2019-06-17Support parsing a Regexp literal with 'o' optionRyan Lopopolo
CRuby supports a 'o' `Regexp` option for `Regexp` literals, e.g. `/foo/o` that disables multiple interpolation passes. This commit adds support for parsing such literals. Nothing is done with the option, it is consumed and ignored by the parser.

2019-05-16Enable `YYSTACK_USE_ALLOCA`.Yukihiro "Matz" Matsumoto
It used heap allocated memory for the parser stack, but there's possibility of parser termination by exceptions. In that case, the parser stack memory is leaked. We were afraid of stack consumption, but parser stack size is only 4KB, so we don't have to worry about it (at least for the parser).

2019-04-01Avoid keeping pointers from `mrb_sym2name_len()`; fix #4342Yukihiro "Matz" Matsumoto
The addresses for packed inline symbols reference `mrb->symbuf` that could be overridden by the later call of `mrb_sym2name_len`. Since file names in call stack information are kept as symbols, keeping the address in the C structures could cause problems like #4342. This changes small incompatible changes in function prototypes: * `mrb_parser_get_filename`: return value changed to `mrb_sym`. * `mrb_debug_get_filename`: add `mrb_state*` as a first argument. * `mrb_debug_get_line`: ditto. I believe above functions are almost internal, and no third-party mrbgem use them.
