2015-12-16[ARM] Add support for thumb1 pcrop relocations.Mickael Guene1-0/+5
To support thumb1 execute-only code we need to support four new relocations (R_ARM_THM_ALU_ABS_G0_NC, R_ARM_THM_ALU_ABS_G1_NC, R_ARM_THM_ALU_ABS_G2_NC and R_ARM_THM_ALU_ABS_G3_NC). These relocations allow the static linker to finalize construction of symbol address. Typical sequence of code to get address of the symbol foo is then the following : movs r3, #:upper8_15:#foo lsls r3, #8 adds r3, #:upper0_7:#foo lsls r3, #8 adds r3, #:lower8_15:#foo lsls r3, #8 adds r3, #:lower0_7:#foo This will give following sequence of text and relocations after assembly : 4: 2300 movs r3, #0 4: R_ARM_THM_ALU_ABS_G3_NC foo 6: 021b lsls r3, r3, #8 8: 3300 adds r3, #0 8: R_ARM_THM_ALU_ABS_G2_NC foo a: 021b lsls r3, r3, #8 c: 3300 adds r3, #0 c: R_ARM_THM_ALU_ABS_G1_NC foo e: 021b lsls r3, r3, #8 10: 3300 adds r3, #0 10: R_ARM_THM_ALU_ABS_G0_NC foo
