When cmodel=extreme, add macro implementation and fix problems with explicit relos implementation. |

Message

Lulu Cheng Jan. 29, 2024, 8:21 a.m. UTC

  When cmodel=extreme, since the symbol address is obtained through four instructions,
errors may occur in some cases during linking. Xi Ruoyao fixes this problem.

https://github.com/loongson/la-abi-specs/blob/release/laelf.adoc#extreme-code-model


v4 -> v5:
  1. Modify code format.
  2. Add the implementation patch submitted by Xi Ruoyao about '-mcmodel=extreme -mexplicit-relocs=always'.

v3 -> v4:
  1. Add macro support for TLS symbols
  2. Added support for loading __get_tls_addr symbol address using call36.
  3. Merge template got_load_tls_{ld/gd/le/ie}.
  4. Enable explicit reloc for extreme TLS GD/LD with -mexplicit-relocs=auto.


v2 -> v3:
  1. Modify the detection rules of a test case.

v1 -> v2:
  1. Use the temporarily allocated registers as intermediate registers to implement the extreme macro.
  2. Fixed bugs in v1 test cases.



Lulu Cheng (4):
  LoongArch: Merge template got_load_tls_{ld/gd/le/ie}.
  LoongArch: Add the macro implementation of mcmodel=extreme.
  LoongArch: Enable explicit reloc for extreme TLS GD/LD with
    -mexplicit-relocs=auto.
  LoongArch: Added support for loading __get_tls_addr symbol address
    using call36.

Xi Ruoyao (1):
  LoongArch: Don't split the instructions containing relocs for extreme
    code model.
