| Summary | 0007237: Make FFI work on 64 bit platforms | |||||||||||
| Description |
FFI has a number of 32 bit dependencies that prevent operation on 64 bit point size machines. Details were reported on the vm-dev list: http://lists.squeakfoundation.org/pipermail/vm-dev/2008-May/001945.html [^] Overall changes involve: - Add FFIPlugin>>primitiveSizeOfPointer for runtime address size check - ExternalAddress is either 4 or 8 bytes wide, initialized at image startup - Remove all casts from pointer to int for FFI plugin and interpreter (VM minor version bump) - Recompile all methods with cdecl or apicall pragmas (must to done for any image to run properly on 64 bit host) |

FFI-primitiveFFIIntegerAt-dtl-M6987-M7237.1.cs is a fix for an FFI issue reported in Mantis 6987 in the test cases FFITestCase.st (see attachments to 0006987). This fix should be applied after the 64-bit FFI updates in order to fully resolve the issues in 0006987. Note that FFI-primitiveFFIIntegerAt-dtl-M6987-M7237.1.cs requires an update to sqMemoryAccess.h in the platform sources. |

This issue affects VM, a plugin in VMMaker, the image, and the external FFI package. VM issues are a prerequisite to fixing the rest, so recategorize to "VM" and assign it to myself. |
