[Vm-dev] platforms/unix/vm *.c vs platform and build type

[gettimothy]

Thank you Eliot.

In the interests of time, I think I will just handle each configuration as it comes. 

I will add your information to the new configuration step-by-step Help book.


cheers.

to build type and platform?

If not, I will assemble one by hand, but I don't want to duplicate work that has already been done.

For example...

linux32x86 squeak.cog.v3 builds fine with sqUnixMemory.c however squeak.cog.spur requires sqUnixSpurMemory.c 

I suspect all the relationships are encoded in the configure and mvm scripts. If they are documented elsewhere, it will save some work.




Actually in the Makefiles, and in tests on manifest defines in the sources.  So...in e.g. build.macos32x86/common/Makefile.vm you find 
...
OSXCOMMONDIR:=$(PLATDIR)/iOS/vm/Common

...
XEX:=%/sqSqueakMainApplication+screen.m %/sqMacV2Window.m \
     %/SqViewBitmapConversion.m %/sqSqueakOSXCGView.m
OSXSRC=$(wildcard $(OSXDIR)/*.c) $(wildcard $(OSXDIR)/*.m) \
        $(wildcard $(OSXCOMMONDIR)/*.c) $(wildcard $(OSXCOMMONDIR)/*.m) \
        $(wildcard $(OSXCLASSESDIR)/*.c) $(wildcard $(OSXCLASSESDIR)/*.m)
OSXSRC:=$(filter-out $(XEX),$(OSXSRC)) UNIXSRC:=$(addprefix $(UNIXVMDIR)/,aio.c sqUnixHeartbeat.c sqUnixSpurMemory.c \

                     sqUnixThreads.c sqUnixVMProfile.c)


and in platforms/unix/vm/sqUnixSpurMemory.c you find


#if SPURVM

...
#endif


and in platforms/iOS//vm/Common/sqMacV2Memory.c you find
#include "sq.h"
#if !SPURVM

...
#endif




So that on the Mac v3 sqUnixSpurMemory..o is empty and sqMacV2Memory..o is not, but on the Mac Spur vice verse.


Likewise for platforms/unix/vm/sqUnixSpurMemory.c & platforms/unix/vm/sqUnixMemory.c.  Use the source Luke!


Which is to say that I try and use manifest constants defined in *src/vm/interp.h to define which features to include.  e.g. Compare src/v/interp.h with spursrc/vm/interp.h:


McStalker.oscogvm$ diff {src,spursrc}/vm/interp.h
10c10
< #define BaseHeaderSize 4
---
> #define BaseHeaderSize 8
35a36
> #define SPURVM 1



or spursrc/vm/interp.h with spur64src/vm/interp.h

McStalker.oscogvm$ diff {spursrc,nsspursrc}/vm/interp.h

etc.


Putting stuff in config files is sadistic.  I wouldn't do that.  It needs to be in the source.
