dearblue e9ceb865b6 Fix MRB_ENDIAN_BIG is always defined, if byte order macro is not defined 2018-12-22 20:37:51 +09:00
Yukihiro "Matz" Matsumoto ed2bc5d4ed Simplify MRB_ENDIAN_BIG macro definition; ref #4190 
`cpp` does not raise error on undefined macro access in condition.
 2018-12-21 09:28:19 +09:00
Yukihiro "Matz" Matsumoto f5537912ab Define MRB_ENDIAN_BIG automatically; ref #4190 
You had to define this macro on big endian platforms, but it is very
error-prone. So define the macro automatically if possible.

Yukihiro "Matz" Matsumoto 83f2654bac Do not use MRB_METHOD_TABLE_INLINE by default; fix #3924 
It was default on Linux. Abandoned for 2 reasons:

* some cross-platform compiler defines `__linux__` even on bare metal
  environment (RTL8196 (MIPS big endian soc) for example).

* some compilers do not align functions pointers so that we need to
  specify `-falign-functions=n` (where n>1). It's not suitable for
  default configuration.

By our measurement, `mrbtest` consumes 400KB less memory. So if your
target machine is memory tight, add the following command-line options
to `GCC` (unfortunately `clang` does not support `-falign-functions`).

`-falign-functions=2 -DMRB_METHOD_TABLE_INLINE`
 2018-01-25 14:22:01 +09:00
Yukihiro "Matz" Matsumoto 8f2c62407c Add MRB_METHOD_TABLE_INLINE option. 
Now the method tables (in classes/modules and caches) keeps C function
pointers without wrapping in `struct RProc` objects. For the sake of
portability, `mrb_method_t` is represented by the struct and union, but
if the most significant bit of the pointer is not used by the platform,
`mrb_method_t` should be packed in `uintptr_t` to reduce memory usage.

`MRB_METHOD_TABLE_INLINE` is turned on by default for linux.

Yukihiro "Matz" Matsumoto f0f4a1088a Make the default integer size to be MRB_INT64 on 64bit systems; close #3800 
Unless `MRB_NAN_BOXING` is specified.

Yukihiro "Matz" Matsumoto 4440566b95 DISABLE_STDIO/ENABLE_DEBUG macros to rename; close #3014 
changes:
 * rename DISABLE_STDIO -> MRB_DISABLE_STDIO
 * rename ENABLE_DEBUG -> MRB_ENABLE_DEBUG_HOOK
 * no more opposite macro definitions (e.g. ENABLE_STDIO, DISABLE_DEBUG).
 * rewrite above macro references throughout the code.
 * update documents

Yukihiro "Matz" Matsumoto 6b956f1c1b use __init_array_start to determine readonly data section; 
b72e94f used _etext and _edata to distinguish C string literals from heap allocated strings,
but using _edata, global char arrays may be considered as string literals.  to avoid the issue,
we have to use __init_array_start, which might be less portable.  you can still use _edata, by
using MRB_NO_INIT_ARRAY_START.
 2014-10-02 09:27:39 +09:00
Yukihiro "Matz" Matsumoto b72e94fa6b mrbconf.h option MRB_USE_ETEXT_EDATA to reduce memory. 
on platforms with _etext and _edata, mruby can distinguish string literals so that it avoids memory allocation to copy them.
for example, on my Linux box (x86 32bit), memory consumed by mrbtest decreased from 8,168,203 to 8,078,848 (reduced 88KB).
 2014-09-30 23:48:57 +09:00
Yukihiro "Matz" Matsumoto 206f89e209 add MRB_API modifiers to mruby API functions 2014-08-04 00:47:08 +09:00
take_cheeze 62f41ddd3b Add fixed state atexit stack feature. 
Adds following macros:
* MRB_FIXED_STATE_ATEXIT_STACK (not defined by default)
  * When defined enables fixed state atexit stack.
* MRB_FIXED_STATE_ATEXIT_STACK_SIZE (default value: 5)
  * This macro will be ignored when `MRB_FIXED_STATE_ATEXIT_STACK` isn't defined.
  * When `mrb_state_atexit` is called more than this value it will raise runtime error.

cubicdaiya 67de10bfcb use C style comments instead of C++ style comments 
According to CONTRIBUTING.md,

Don't use C++ style comments

 /* This is the prefered comment style */

Use C++ style comments only for temporary comment e.g. commenting out some code lines.

Yukihiro "Matz" Matsumoto 07b8a5b042 Make mrb->arena variable sized. Use MRB_GC_FIXED_ARENA for old behavior. 
You will not see "arena overflow" error anymore, but I encourage gem authors
to check your gems with MRB_GC_FIXED_ARENA to avoid memory broat.

Masaki Muranaka cbcd39bae4 Avoid defining MRB_INT16 adn MRB_INT64 at the same time. This is a poka-yoke. 2013-04-26 11:41:34 +09:00
Masaki Muranaka 59c8d6c13a Remove str_to_mrb_int(). There is some reasons. 
It is not used in the core.
 It does not have mrb_ prefix.
 strtol() is slightly heavy and we have similar API.

Yukihiro Matz Matsumoto 228687cfff experimental MRB_INT16 added 2013-03-14 23:12:00 +09:00
Masaki Muranaka 1ffc9ba325 Define type mrb_bool. It is typedef-ed to _Bool on C99, unsigned int on MSVC. 
It is safer than applying 1bit bit-fields to signed int.

For forward compatibility, you should substiture only 1 or 0 for the variable typed mrb_bool.

Masaki Muranaka e2d31ba3f3 Rename STR_BUF_MIN_SIZE to MRB_STR_BUF_MIN_SIZE. Make it configurable. 2013-03-12 17:10:18 +09:00
Cremno f719b0e7ff define and use print format macros for mrb_int 
For portability: %ld can't be used to print a 64-bit mrb_int on
WIN(32|64) because long is 32-bit wide.
