2017-03-19Fixed OP_RESCUE code generation bug; fix #3519Yukihiro "Matz" Matsumoto
916b8e let code executed with mrb->exc set, and may cause a crash like #3519. Instead modified OP_RESCUE again. To retrieve the exception object, we use `OP_RESCUE R(A), 0, 0` (old behavior). To compare the exception object and the class, we use `OP_RESCUE R(A), R(B), 1`. The reason we use OP_RESCUE for two instruction switched by operand C is to save the instruction space. As a result, the following code: ```ruby begin raise "a" rescue TypeError p 1 rescue RuntimeError p 2 end ``` will be compiled as: ``` irep 0x55cd1f565cb0 nregs=4 nlocals=1 pools=1 syms=4 reps=0 file: - 2 000 OP_ONERR 005 2 001 OP_LOADSELF R1 2 002 OP_STRING R2 L(0) ; "a" 2 003 OP_SEND R1 :raise 1 2 004 OP_JMP 023 2 005 OP_RESCUE R1 3 006 OP_GETCONST R2 :TypeError 3 007 OP_RESCUE R1 R2 cont 3 008 OP_JMPIF R2 010 3 009 OP_JMP 014 4 010 OP_LOADSELF R1 4 011 OP_LOADI R2 1 4 012 OP_SEND R1 :p 1 4 013 OP_JMP 024 5 014 OP_GETCONST R2 :RuntimeError 5 015 OP_RESCUE R1 R2 cont 5 016 OP_JMPIF R2 018 5 017 OP_JMP 022 6 018 OP_LOADSELF R1 6 019 OP_LOADI R2 2 6 020 OP_SEND R1 :p 1 6 021 OP_JMP 024 6 022 OP_RAISE R1 6 023 OP_POPERR 1 6 024 OP_STOP ```

2017-03-13Need to copy argv since it may be reallocated; fix #3500Yukihiro "Matz" Matsumoto
The argv for `mrb_yield_with_class()` should not be on mruby stack. Note the result from `mrb_get_args("*")` is on the stack.
2017-03-13OP_BLKPUSH is invalid outside of methods; fix #3501Yukihiro "Matz" Matsumoto
2017-03-12Generate new OP_RESCUE; fix #3487Yukihiro "Matz" Matsumoto
The old OP_RESCUE took one operand A, which specifies a class to match with the exception. The new OP_RESCUE takes tree operands: A: the register to hold exception B: the matching exception; the match result will be stored here. C: the continuation; if C is zero, the exception will be stored to R(A) otherwise, the value from R(A) is used as a exception. Thus, ```ruby begin raise "a" rescue TypeError p 1 rescue RuntimeError p 2 end ``` will be compiled as ``` irep 0x557a06667aa0 nregs=4 nlocals=1 pools=1 syms=4 reps=0 file: /tmp/e.rb 2 000 OP_ONERR 005 2 001 OP_LOADSELF R1 2 002 OP_STRING R2 L(0) ; "a" 2 003 OP_SEND R1 :raise 1 2 004 OP_JMP 022 3 005 OP_GETCONST R2 :TypeError 3 006 OP_RESCUE R1 R2 3 007 OP_JMPIF R2 009 3 008 OP_JMP 013 4 009 OP_LOADSELF R1 4 010 OP_LOADI R2 1 4 011 OP_SEND R1 :p 1 4 012 OP_JMP 023 5 013 OP_GETCONST R2 :RuntimeError 5 014 OP_RESCUE R1 R2 cont 5 015 OP_JMPIF R2 017 5 016 OP_JMP 021 6 017 OP_LOADSELF R1 6 018 OP_LOADI R2 2 6 019 OP_SEND R1 :p 1 6 020 OP_JMP 023 6 021 OP_RAISE R1 6 022 OP_POPERR 1 6 023 OP_STOP ``` The new VM can accept old OP_RESCUE. The mruby compatible VM (namely mruby/c) should be updated to support the new OP_RESCUE behavior.
