Pushed to r14-8717...r14-8721.
在 2024/1/29 下午4:21, Lulu Cheng 写道:
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.
