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. gcc/config/loongarch/loongarch-protos.h | 1 + gcc/config/loongarch/loongarch.cc | 265 ++++++++++-------- gcc/config/loongarch/loongarch.md | 125 ++++++--- gcc/config/loongarch/predicates.md | 12 + .../loongarch/cmodel-extreme-mi-thunk-1.C | 11 + .../loongarch/cmodel-extreme-mi-thunk-2.C | 6 + .../loongarch/cmodel-extreme-mi-thunk-3.C | 6 + .../gcc.target/loongarch/attr-model-5.c | 8 + .../gcc.target/loongarch/cmodel-extreme-1.c | 18 ++ .../gcc.target/loongarch/cmodel-extreme-2.c | 7 + .../explicit-relocs-extreme-auto-tls-ld-gd.c | 5 + .../explicit-relocs-medium-auto-tls-ld-gd.c | 5 + ...icit-relocs-medium-call36-auto-tls-ld-gd.c | 5 + .../loongarch/func-call-extreme-1.c | 14 +- .../loongarch/func-call-extreme-2.c | 29 +- .../loongarch/func-call-extreme-3.c | 2 +- .../loongarch/func-call-extreme-4.c | 2 +- .../loongarch/func-call-extreme-5.c | 7 + .../loongarch/func-call-extreme-6.c | 7 + .../gcc.target/loongarch/tls-extreme-macro.c | 35 +++ 20 files changed, 375 insertions(+), 195 deletions(-) create mode 100644 gcc/testsuite/g++.target/loongarch/cmodel-extreme-mi-thunk-1.C create mode 100644 gcc/testsuite/g++.target/loongarch/cmodel-extreme-mi-thunk-2.C create mode 100644 gcc/testsuite/g++.target/loongarch/cmodel-extreme-mi-thunk-3.C create mode 100644 gcc/testsuite/gcc.target/loongarch/attr-model-5.c create mode 100644 gcc/testsuite/gcc.target/loongarch/cmodel-extreme-1.c create mode 100644 gcc/testsuite/gcc.target/loongarch/cmodel-extreme-2.c create mode 100644 gcc/testsuite/gcc.target/loongarch/explicit-relocs-extreme-auto-tls-ld-gd.c create mode 100644 gcc/testsuite/gcc.target/loongarch/explicit-relocs-medium-auto-tls-ld-gd.c create mode 100644 gcc/testsuite/gcc.target/loongarch/explicit-relocs-medium-call36-auto-tls-ld-gd.c create mode 100644 gcc/testsuite/gcc.target/loongarch/func-call-extreme-5.c create mode 100644 gcc/testsuite/gcc.target/loongarch/func-call-extreme-6.c create mode 100644 gcc/testsuite/gcc.target/loongarch/tls-extreme-macro.c -- 2.39.3
