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

2015-10-22Add R_X86_64_[REX_]GOTPCRELX support to gas and ldH.J. Lu2-4/+15
This patch adds support for the R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations proposed in https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0 to gas and ld. It updates gas to generate R_X86_64_GOTPCRELX, R_X86_64_REX_GOTPCRELX if there is a REX prefix, relocation for memory operand, foo@GOTPCREL(%rip). With the locally defined symbol, foo, we convert mov foo@GOTPCREL(%rip), %reg to lea foo(%rip), %reg and convert call/jmp *foo@GOTPCREL(%rip) to nop call foo/jmp foo nop When PIC is false, convert test %reg, foo@GOTPCREL(%rip) to test $foo, %reg and convert binop foo@GOTPCREL(%rip), %reg to binop $foo, %reg where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions. bfd/ * elf64-x86-64.c: Include opcode/i386.h.

2015-10-22Add R_386_GOT32X support to gas and ldH.J. Lu2-0/+6
This patch adds support for the R_386_GOT32X relocation proposed in https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I to gas and ld. It updates gas to generate R_386_GOT32X relocation for memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax" with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be transformed to "lea foo, %eax". With the locally defined symbol, foo, we convert mov foo@GOT[(%reg1)], %reg2 to lea foo[@GOTOFF(%reg1)], %reg2 and convert call/jmp *foo@GOT[(%reg)] to nop call foo/jmp foo nop When PIC is false, convert test %reg1, foo@GOT[(%reg2)] to test $foo, %reg1 and convert binop foo@GOT[(%reg1)], %reg2 to binop $foo, %reg2 where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions. bfd/ * elf32-i386.c: Include opcode/i386.h.

Taking them out showed a bug in the powerpc64 backend with .branch_lt being removed from output_bfd but not from previously set up segment section maps.

2015-02-20S390: Support new vector register sectionsAndreas Arnez2-0/+9
The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15 include the existing 64-bit wide floating point registers. The Linux kernel presents the vector registers as two additional register sets, one for the right halves of v0-v15 and another one for the full registers v16-v31. Thus a new core file may contain two new register note sections, and this patch adds support to binutils for them. bfd/ * elf-bfd.h (elfcore_write_s390_vxrs_low): Add prototype.
