* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Created new central header "emu.h"; this should be included by pretty much any driver or device as the first include. This file in turn includes pretty much everything a driver or device will need, minus any other devices it references. Note that emu.h should *never* be included by another header file. - Updated all files in the core (src/emu) to use emu.h. - Removed a ton of redundant and poorly-tracked header includes from within other header files. - Temporarily changed driver.h to map to emu.h until we update files outside of the core. Added class wrapper around tagmap so it can be directly included and accessed within objects that need it. Updated all users to embed tagmap objects and changed them to call through the class. Added nicer functions for finding devices, ports, and regions in a machine: machine->device("tag") -- return the named device, or NULL machine->port("tag") -- return the named port, or NULL machine->region("tag"[, &length[, &flags]]) -- return the named region and optionally its length and flags Made the device tag an astring. This required touching a lot of code that printed the device to explicitly fetch the C-string from it. (Thank you gcc for flagging that issue!)

And added a casting operator to const char * for seamless use in most functions that take plain old C strings. Changed all uses of astring to use the object directly on the stack or embedded in objects instead of explicitly allocating and deallocating it. Removed a lot of annoying memory management code as a result. Changed interfaces that accepted/returned an astring * to use an astring & instead. Removed auto_alloc_astring(machine). Use auto_alloc(machine, astring) instead.

Renamed mamecore.h -> emucore.h. New C++-aware memory manager, implemented in emualloc.*. This is a simple manager that allows you to add any type of object to a resource pool. Most commonly, allocated objects are added, and so a set of allocation macros is provided to allow you to manage objects in a particular pool: pool_alloc(p, t) = allocate object of type 't' and add to pool 'p' pool_alloc_clear(p, t) = same as above, but clear the memory first pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type 't' and add to pool 'p' pool_alloc_array_clear(p, t, c) = same, but with clearing pool_free(p, v) = free object 'v' and remove it from the pool Note that pool_alloc[_clear] is roughly equivalent to "new t" and pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also note that pool_free works for single objects and arrays. There is a single global_resource_pool defined which should be used for any global allocations. It has equivalent macros to the pool_* macros above that automatically target the global pool. In addition, the memory module defines global new/delete overrides that access file and line number parameters so that allocations can be tracked. Currently this tracking is only done if MAME_DEBUG is enabled. In debug builds, any unfreed memory will be printed at the end of the session. emualloc.h also has #defines to disable malloc/free/realloc/calloc. Since emualloc.h is included by emucore.h, this means pretty much all code within the emulator is forced to use the new allocators. Although straight new/delete do work, their use is discouraged, as any allocations made with them will not be tracked. Changed the familar auto_alloc_* macros to map to the resource pool model described above. The running_machine is now a class and contains a resource pool which is automatically destructed upon deletion. If you are a driver writer, all your allocations should be done with auto_alloc_*. Changed all drivers and files in the core using malloc/realloc or the old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros instead, or the global_alloc_* macros if necessary. Added simple C++ wrappers for astring and bitmap_t, as these need proper constructors/destructors to be used for auto_alloc_astring and auto_alloc_bitmap. Removed references to the winalloc prefix file. Most of its functionality has moved into the core, save for the guard page allocations, which are now implemented in osd_alloc and osd_free.

* Added casts to ensure proper values are passed to the ctype.h functions. Aaron Giles2009-06-251-3/+3

* Bulk change alert. Aaron Giles2009-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This update changes the way we handle memory allocation. Rather than allocating in terms of bytes, allocations are now done in terms of objects. This is done via new set of macros that replace the malloc_or_die() macro: alloc_or_die(t) - allocate memory for an object of type 't' alloc_array_or_die(t,c) - allocate memory for an array of 'c' objects of type 't' alloc_clear_or_die(t) - same as alloc_or_die but memset's the memory to 0 alloc_array_clear_or_die(t,c) - same as alloc_array_or_die but memset's the memory to 0 All original callers of malloc_or_die have been updated to call these new macros. If you just need an array of bytes, you can use alloc_array_or_die(UINT8, numbytes). Made a similar change to the auto_* allocation macros. In addition, added 'machine' as a required parameter to the auto-allocation macros, as the resource pools will eventually be owned by the machine object. The new macros are: auto_alloc(m,t) - allocate memory for an object of type 't' auto_alloc_array(m,t,c) - allocate memory for an array of 'c' objects of type 't' auto_alloc_clear(m,t) - allocate and memset auto_alloc_array_clear(m,t,c) - allocate and memset All original calls or auto_malloc have been updated to use the new macros. In addition, auto_realloc(), auto_strdup(), auto_astring_alloc(), and auto_bitmap_alloc() have been updated to take a machine parameter. Changed validity check allocations to not rely on auto_alloc* anymore because they are not done in the context of a machine. One final change that is included is the removal of SMH_BANKn macros. Just use SMH_BANK(n) instead, which is what the previous macros mapped to anyhow.
