2016-12-21bfd: aarch64: fix word and arrdess size declaration in ilp32 modeYury Norov2-4/+11
ILP32 has 32-bit word and address, but currently they declared as 64-bit in bfd_aarch64_arch_ilp32, which breaks further logic of bfd. This patch fixes it. Glibc testsuite build with patched binutils shows that next tests stop to fail: iconvdata/mtrace-tst-loading iconvdata/tst-loading iconvdata/tst-tables localedata/mtrace-tst-leaks localedata/tst-leaks posix/tst-getaddrinfo4 posix/tst-getaddrinfo5 posix/tst-regex2

2016-12-20Re-work RISC-V gas flags: now we just support -mabi and -marchAndrew Waterman2-2/+7
We've decided to standardize on two flags for RISC-V: "-march" sets the target architecture (which determines which instructions can be generated), and "-mabi" sets the target ABI. We needed to rework this because the old flag set didn't support soft-float or single-float ABIs, and didn't support an x32-style ABI on RISC-V. Additionally, we've changed the behavior of the -march flag: it's now a lot stricter and only parses things we can actually understand. Additionally, it's now lowercase-only: the rationale is that while the RISC-V ISA manual specifies that ISA strings are case-insensitive, in Linux-land things are usually case-sensitive. Since this flag can be used to determine library paths, we didn't want to bake some case-insensitivity in there that would case trouble later. This patch implements these two new flags and removes the old flags that could conflict with these. There wasn't a RISC-V release before, so we want to just support a clean flag set. include/ * elf/riscv.h (EF_RISCV_SOFT_FLOAT): Don't define. (EF_RISCV_FLOAT_ABI, EF_RISCV_FLOAT_ABI_SOFT): Define.

2016-12-20Rework RISC-V relocationsAndrew Waterman6-17/+274
Before this commit we didn't cleanly support CFI directives because the internal offsets used to get relaxed which broke them. This patch significantly reworks how we handle linker relaxations: * DWARF is now properly supported * There is a ".option norelax" to disable relaxations, for when users write assembly that can't be relaxed (if it's to be later patched up, for example). * There is an additional _RELAX relocation that specifies when previous relocations can be relaxed. We're in the process of documenting the RISC-V ELF ABI, which will include documentation of our relocations https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md but we expect that this relocation set will remain ABI compatible in the future (ie, it's safe to release).

This is a mixed bag of format changes: * Replacing constants with macros (0xffffffff with MINUS_ONE, for example). There's one technically functional change in here (some MINUS_ONEs are changed to 0), but it only changes the behavior of an otherwise-unused field. * Using 0 instead of 0x0 in the relocation table. * There were some missing spaces before parens, the spaces have been added. * A handful of comments are now more descriptive. * A bunch of whitespace-only changes, mostly alignment and brace newlines. bfd/ * elfnn-riscv.c: Formatting and comment fixes throughout. * elfxx-riscv.c: Likewise.

2016-12-14ld: aarch64: fix TLS relaxation where TCB_SIZE is usedYury Norov2-5/+20
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for ilp32. During relaxation, ld goes to do a replace: bl __tls_get_addr => add R0, R0, TCB_SIZE But actual implementation is: bfd_putl32 (0x91004000, contents + rel->r_offset + 4); Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32. The possible fix for it is: bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4); But ilp32 also needs w-registers, so it's simpler to put proper instruction in #if/#else condition. There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new tests added for ilp32 mode to test it.

RX does horrible fudges to PT_LOAD p_vaddr, that affect the testsuite and mean the target won't support dynamic objects. The latter probably doesn't matter too much since RX is an embedded target, but it's easy to stop some of the fudges in order to reduce special cases for RX in the testsuite.
