// REQUIRES: arm
Initial support for ARM in lld. Add support for an ARM Target and the initial set of relocations and PLT entries that are necessary for an ARM only hello world to link. This has been tested against an ARM only sysroot from the 4.2.0 CodeSourcery Lite release. Tests have been added to test/ELF for the support that has been implemented. Main limitations: - No Thumb support - Relocations incomplete - No C++ exceptions support - No TLS support - No range extension or interworking veneer (thunk) support - No Build Attribute support - No Big-endian support The deprecated relocations R_ARM_PLT32 and R_ARM_PC24 have been implemented as these are used by the 4.2.0 CodeSourcery Lite release. llvm-svn: 271993

Add initial support for Thumb for ARMv7a Add support for the R_ARM_THM relocations used in the objects present in arm-linux-gnueabihf-gcc. These are: R_ARM_THM_CALL R_ARM_THM_JUMP11 R_ARM_THM_JUMP19 R_ARM_THM_JUMP24 R_ARM_THM_MOVT_ABS R_ARM_THM_MOVW_ABS_NC Interworking between ARM and Thumb is partially supported with BLX. The R_ARM_CALL relocation for ARM instructions and R_ARM_THM_CALL relocation for Thumb instructions will write out a BL or BLX depending on the state of the Target. Assumptions: - Availability of BLX and extended range of Thumb 4-byte Branch instructions. - In relocateOne if (Val & 0x1) == 1 target is Thumb, 0 is ARM. This will hold for objects that comply with the ABI for the ARM architecture. This is sufficient for hello world to work with a recent arm-linux-gnueabihf distribution. Limitations: No interworking for R_ARM_JUMP24, R_ARM_THM_JUMP24, R_ARM_THM_JUMP19 and the deprecated R_ARM_PLT32 and R_ARM_PC24 instructions as these cannot be written out as a BLX and need a state change thunk. No range extension thunks. The R_ARM_JUMP24 and R_ARM_THM_CALL have a range of 16Mb llvm-svn: 272881

Initial support for ARM in lld. Add support for an ARM Target and the initial set of relocations and PLT entries that are necessary for an ARM only hello world to link. This has been tested against an ARM only sysroot from the 4.2.0 CodeSourcery Lite release. Tests have been added to test/ELF for the support that has been implemented. Main limitations: - No Thumb support - Relocations incomplete - No C++ exceptions support - No TLS support - No range extension or interworking veneer (thunk) support - No Build Attribute support - No Big-endian support The deprecated relocations R_ARM_PLT32 and R_ARM_PC24 have been implemented as these are used by the 4.2.0 CodeSourcery Lite release. llvm-svn: 271993

[LLD][ELF][ARM] Fix support for SBREL type relocations With this patch lld recognizes ARM SBREL relocations. R_ARM*_MOVW_BREL relocations are not tested because they are not used. Patch by Tamas Petz Differential Revision: https://reviews.llvm.org/D74604
2020-02-19 01:53:26 +08:00
/// 0x20004
Initial support for ARM in lld. Add support for an ARM Target and the initial set of relocations and PLT entries that are necessary for an ARM only hello world to link. This has been tested against an ARM only sysroot from the 4.2.0 CodeSourcery Lite release. Tests have been added to test/ELF for the support that has been implemented. Main limitations: - No Thumb support - Relocations incomplete - No C++ exceptions support - No TLS support - No range extension or interworking veneer (thunk) support - No Build Attribute support - No Big-endian support The deprecated relocations R_ARM_PLT32 and R_ARM_PC24 have been implemented as these are used by the 4.2.0 CodeSourcery Lite release. llvm-svn: 271993
