mold 1.9.0
New features
- mold gained support for the three new targets: 32-bit PowerPC, SH-4 and DEC Alpha. Each porting work didn't take more than a few days for us to complete, which demonstrate how portable the mold linker is. You can typically port mold to a new target just by writing a few hundreds lines of target-specific code. See
arch-*.ccfiles in mold/elf/ directory to see how target-specific code actually looks like. (651adad, 3411e17, 6231510)
Bug fixes and compatibility improvements
- In a rare occasion, a statically-initialized function pointer might get a wrong address in a statically-linked executable. This bug has been fixed. (ccd47db)
- Fixed a
-gdb-indexoption's crash bug on big-endian hosts. (3c96828) - [RISC-V] mold rewrote machine instructions in a wrong way as a result of a wrong
R_RISCV_HI20relaxation if the output file was being linked against the high address. It's not a problem for user-land programs, but kernels linked with mold could crash due to this bug. This bug has been fixed. (3c96828)
