2015-12-16[ARM] Add support for thumb1 pcrop relocations.Mickael Guene5-0/+168
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

2015-12-07ld: relax alignment requirements of compressed .debug_* section checksJan Beulich3-2/+7
This fixes a failure of the gabinormal linking test on some distros (where e.g. crt1.o has a .debug_aranges section with larger alignment).
2015-12-04Optimize R_386_GOT32/R_386_GOT32X only if addend is 0H.J. Lu13-0/+169
Linker can't optimize R_386_GOT32 and R_386_GOT32X relocations if addend isn't 0. It isn't valid to convert movl foo@GOT+1(%ecx), %eax to leal foo@GOTOFF+1(%ecx), %eax nor to convert movq foo@GOTPCREL+1(%rip), %rax to leaq foo(%rip), %rax for x86-64. We should check if addend is 0 before optimizing R_386_GOT32 and R_386_GOT32X relocations. Testcases are added for i386 and x86-64. bfd/ * elf32-i386.c (elf_i386_convert_load): Skip if addend isn't 0.

2015-12-01Properly check symbol defined by assignment in linker scriptH.J. Lu9-0/+96
Symbol defined by a linker assignment may have type bfd_link_hash_new or bfd_link_hash_undefined. And h->def_regular is always set. elf_i386_convert_load and elf_x86_64_convert_load should check h->def_regular as well as bfd_link_hash_undefined and bfd_link_hash_new to see if a symbol is defined by a linker script. bfd/ PR ld/19319 * elf32-i386.c (elf_i386_convert_load): Check h->def_regular instead of bfd_link_hash_new. * elf64-x86-64.c (elf_x86_64_convert_load): Likewise.

2015-09-29Adjust the output section size to skip gap fillsH.J. Lu4-0/+34
In objcopy, copy_object calls copy_section to copy contents of input section to output section. When --gap-fill= is used, objcopy extends the size of output sectios to fill gaps between output sections with gap fills. In this case, we adjust the output section size to skip gap files to avoid reading beypond the input section buffer before calling copy_section and restore the output section size after input sections have been copied. binutils/ PR binutils/19005 * objcopy.c (copy_object): Adjust the output section size to skip gap fills between sections when copying from input sections to output sections. ld/testsuite/ PR binutils/19005 * ld-elf/pr19005.d: New file. * ld-elf/pr19005.s: Likewise. * ld-elf/pr19005.t: Likewise.
