Subject: [PR ld/22263][PR ld/25694] RISC-V: Avoid dynamic TLS relocs in PIE.
X-Git-Url: https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff_plain;h=225df051d3d4cf714d1791b9035966a6686b3f3d;hp=a70d5ba34cb64bbbb7df4f3055cf5b1967bdf61e
[PR ld/22263][PR ld/25694] RISC-V: Avoid dynamic TLS relocs in PIE.
Lots of targets already fixed the TEXTREL problem for TLS in PIE.
* For PR ld/25694,
In the check_reloc, refer to spare and loongarch, they don't need to reserve
any local dynamic reloc for TLS LE in pie/pde, and similar to other targets.
So it seems like riscv was too conservative to estimate the TLS LE before.
Just break and don't goto static_reloc for TLS LE in pie/pde can fix the
TEXTREL problem.
* For PR ld/22263,
The risc-v code for TLS GD/IE in the relocate_section seems same as MIPS port.
So similar to MIPS, pr22570, commits 9143e72c6d4d and 1cb83cac9a89, it seems
also the right way to do the same thing for risc-v.
On risc-v, fixes
FAIL: Build pr22263-1
RISC-V haven't supported the TLS transitions, so will need the same fix (use
bfd_link_dll) in the future.
bfd/
PR ld/22263
PR ld/25694
* elfnn-riscv.c (riscv_elf_check_relocs): Replace bfd_link_pic with
bfd_link_dll for TLS IE. Don't need to reserve the local dynamic
relocation for TLS LE in pie/pde, and report error in pic just like
before.
(riscv_elf_relocate_section): For TLS GD/IE, use bfd_link_dll rather
than !bfd_link_pic in determining the dynamic symbol index. Avoid
the index of -1.
