fix(relinker): report RIP-relative operands of far indirect CALL and JMP
DecodeInstruction returned before reading the ModRM of FF /3 and FF /5, so a far CALL or JMP through a RIP-relative pointer had no RIP-relative displacement. A stub that moved such a JMP copied the displacement without relocating it. The decoder was compared with iced-x86 (AMD decoding) over 3.99 million encodings: every opcode of the legacy, 0F, 0F38 and 0F3A maps under 34 prefix combinations and the VEX 0F, 0F38 and 0F3A maps, each with 48 ModRM forms. Apart from this, it agrees on length, RIP-relative offset, control flow kind and branch target for every valid Zen 2 instruction except near branches with a 66 prefix, recorded as technical debt, and kernel-only returns, which it treats as sequential. Add the comparison's metadata as cases: one RIP-relative encoding per opcode, map and immediate size, every FF /r form, and the branch forms with their flow kind and target. The existing cases check lengths only; a loop or jrcxz decoded as an unconditional jump passed the whole suite.

- The executable file that [relinker](../../../core/relinker/elfpatcher/src/windows/WindowsPeWriter.cpp) generates opens a console when launched, unless it is relinked with `--windows-gui`, which selects the GUI subsystem. A GUI build started from Explorer has no standard output or error handle, so everything it prints is lost, including the entry stub's errors and crash reports (#3282).
|
||||
- Converted Windows main executables [omit `DYNAMIC_BASE`](../../../core/relinker/elfpatcher/src/windows/WindowsPeWriter.cpp) by default, not only with `--windows-fixed-base`: on the console the executable lies inside the 40-bit window that the title's own `sceLibcMspaceCreate` checks (#3043). Relocations are kept, so if `0x140000000` is taken Windows relocates the image, possibly above that window. Verified only on Windows 10.
|
||||
- [SDK memory-management syscall traps](../../../core/relinker/relinker/src/analysis/SyscallScanner.cpp) under `--trap-sdk-syscall-stubs` recognize three exact instruction sequences from [ps5-payload-dev SDK libc/mman.c](https://github.com/ps5-payload-dev/sdk/blob/12cf3dda40/libc/mman.c), observed in Nuvio Maxd 0.5.15 (PPSA99288): syscall 74 and the two syscall 477 paths, with their argument preparation and carry-flag error handling. Matching requires a decoded instruction boundary and the complete sequence inside the scanned code range. Other SDK/compiler output remains rejected. The matched syscall becomes `UD2`; this does not implement mmap or mprotect and a call still faults.
|
||||
- The [instruction decoder](../../../core/relinker/codegen/src/x86/X64InstructionDecoder.cpp) decodes a near CALL, JMP or Jcc with an operand-size prefix (`66`) as Intel does, with a 32-bit or 8-bit displacement and a 64-bit target. AMD processors, the console included, read a 16-bit displacement for `66 E8`, `66 E9` and `66 0F 80`-`8F` and truncate the target of every near branch with that prefix, rel8 forms included, to 16 bits. Compilers do not emit these forms; the relinker's length and target for them do not match the console.
|
||||
- `--to-intel` does not lower RDPRU/MCOMMIT; the [matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp) fails the relink instead.
|
||||
- The length-changing path of the [instruction rewriter](../../../core/relinker/codegen/src/x86/X64InstructionRewriter.cpp) is not used by the [converter](../../../core/relinker/codegen/src/Amd64OnlyConverter.cpp): it does not adjust data-to-code references (relocations, FDEs, jump tables) or segment sizes, so every substitution keeps the instruction length.
|
||||
- A `PT_SCE_RELRO` segment that no `PT_LOAD` covers, the PS4 layout, is [loaded](../../../core/relinker/relinker/src/parsing/ElfReader.cpp) as a read-write `PT_LOAD` and stays writable after relocation; FreeBSD rtld makes `PT_GNU_RELRO` read-only once relocation is done, and what the console does with `PT_SCE_RELRO` is not checked.
