Gareth Rees	1a04431cff	New modulefile prmcw3.c avoids duplication of code between prmcw3i3.c and prmcw3i6.c. ... Implement MutatorContextCheck on Windows. Add AVERT(MutatorContext, context) in PoolAccess and other functions. Document initialization functions MutatorContextInitFault and MutatorContextInitThread and implement them on Windows. Add a union discriminator to MutatorContextStruct on Windows so that we don't accidentally try to get the stack pointer from a fault context, or the exception address from a thread context.

Gareth Rees	4457a77a07	Initialization and checking of mutatorcontext data structures. ... New files prmcix.c and prmcxc.c avoid duplicated code. Copied from Perforce Change: 192562 ServerID: perforce.ravenbrook.com	2016-10-13 23:13:40 +01:00
Gareth Rees	b4a3d0824b	Rename the "protection mutator context" module to "mutator context" (this module handles mutator context decoding for both the protection module and the thread module). ... Rename functions Prot{Can,}StepInstruction to MutatorContext{Can,}StepInstruction so that they follow the naming convention in guide.implc.naming.prefix.program. Move mutator context declarations out of prot.h into new header prmc.h. Correct .assume.null in a couple of places -- it's not safe for MutatorContextStepInstruction to return ResUNIMPL, instead MutatorContextCanStepInstruction should return FALSE.
