| 04:31 | finish moving heap allocation/free functions to the posix syscall apparatus and deprecate the direct assembly implementations of platform_mmap; update the kmem docs to match new function signatures (and remove typos) check-in: 709ffb094d user: lexi tags: trunk | |
| 02:52 | removed sneaky segfault in x86-64 syscall fn where %r8 (the register that contains the pointer to the syscall arguments from the C syscall wrapper, which need to be copied into the correct registers before the kernel is invoked) gets overwritten if the syscall valency > 5, because of overlapping ccall and syscall ABI argument registers - r8 is clobbered by argument 5 and any further attempts to use it as a ptr segfault at best. also modified the report function so that it immediate cancels compilation if a sub-process reports failure. changed allocator function signatures so they can return a condition code if the kernel reports an error; updated example code so it compiles and runs without fault. check-in: e50a476efe user: lexi tags: trunk | |
