Subject: [patch] More Machine->machine changes, add machine to irq callbacks Hi mamedev, Here are two more patches to eliminate Machine globals. The first patch was autogenerated by the attached fixup script. That script has been updated to catch additional cases which it previously missed (when Machine is the last parameter to a function or Machine is used in an assignment). This makes ~50 more files deprecat.h free. A sizable chunk (~20%) of the remaining uses of the Machine global in the drivers are due to irq callbacks for sound and machine updates. Typically such callbacks need to call cpunum_set_input_line, which requires a machine parameter, so if the callbacks don't pass the machine parameter, these routines have no choice but to reference the global variable. The second patch attempts to address most cases of this by adding the machine parameter to the callback interfaces. This allows us to remove #include "deprecat.h" from ~150 files, at the cost of having to fix up hundreds of callbacks. In total, these patches reduced the number of files with deprecat.h from 783 to 575. ~aa

** I would like to thank following people for making this project possible:
|
|
**
|
|
** Beauty Planets - for making a lot of real YM2151 samples and providing
|
|
** additional informations about the chip. Also for the time spent making
|
|
** the samples and the speed of replying to my endless requests.
|
|
**
|
|
** Shigeharu Isoda - for general help, for taking time to scan his YM2151
|
|
** Japanese Manual first of all, and answering MANY of my questions.
|
|
**
|
|
** Nao - for giving me some info about YM2151 and pointing me to Shigeharu.
|
|
** Also for creating fmemu (which I still use to test the emulator).
|
|
**
|
|
** Aaron Giles and Chris Hardy - they made some samples of one of my favourite
|
|
** arcade games so I could compare it to my emulator.
|
|
**
|
|
** Bryan McPhail and Tim (powerjaw) - for making some samples.
|
|
**
|
|
** Ishmair - for the datasheet and motivation.
