2020-01-24RISC-V: Minor cleanup for s extension support.Jim Wilson2-5/+9
Looking at older versions of the patch, I confirmed that the odd comment I referred to earlier was indeed from the removal of the sx support. It also explains an oddly formatted switch statement. This patch fixes both minor problems. bfd/ * elfxx-riscv.c (riscv_get_prefix_class): Format s case like others. (riscv_parse_prefixed_ext): Fix s extension comment and reword to avoid over long line.

This implements register saving and restoring in the __tls_get_addr call stub, so that when glibc supports the optimized tls call stub gcc can generate code that assumes only r0, r12 and of course r3 are changed on a __tls_get_addr call.

2020-01-20x86-64: Fix TLSDESC relaxation for x32H.J. Lu2-19/+94
For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix even if it isn't required. Otherwise linker can’t safely perform GDesc -> IE/LE optimization. X32 TLSDESC sequences can be: 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg ... 67 ff 10 call *x@TLSCALL(%eax) or the same sequence as LP64: 48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg ... ff 10 call *foo@TLSCALL(%rax) We need to support both sequences for x32. For both GDesc -> IE/LE transitions, 67 ff 10 call *x@TLSCALL(%eax) should relaxed to 0f 1f 00 nopl (%rax) For GDesc -> LE transition, 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg should relaxed to 40 c7 c0 fc ff ff ff rex movl $x@tpoff, %reg For GDesc -> IE transition, 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg should relaxed to 40 8b 05 00 00 00 00 rex movl x@gottpoff(%rip), %eax bfd/ PR ld/25416 * elf64-x86-64.c (elf_x86_64_check_tls_transition): Support "rex leal x@tlsdesc(%rip), %reg" and "call *x@tlsdesc(%eax)" in X32 mode.

2020-01-20Don't touch r11 in __tls_get_addr stubAlan Modra2-11/+15
This modifies the special __tls_get_addr stub that checks for a tlsdesc style __tls_index entry and returns early.

2020-01-15PR25384, PowerPC64 ELFv1 copy relocs against function symbolsAlan Modra2-19/+38
Function symbols of course don't normally want .dynbss copies but with some old versions of gcc they are needed to copy the function descriptor. This patch restricts the cases where they are useful to compilers using dot-symbols, and enables the warning regardless of whether a PLT entry is emitted in the executable. PLTs in shared libraries are affected by a .dynbss copy in the executable. bfd/ PR 25384 * elf64-ppc.c (ELIMINATE_COPY_RELOCS): Update comment.

2020-01-13Memory leaks and ineffective bounds checking in wasm_scanAlan Modra2-56/+56
It's always a bad idea to perform arithmetic on an unknown value read from an object file before comparing against bounds. Code like the following attempting to bounds check "len", a 64-bit value, isn't effective because the pointer arithmetic ignores the high 32 bits when compiled for a 32-bit host. READ_LEB128 (len, p, end); if (p + len < p || p + len > end) goto error_return; Instead, perform any arithmetic on known values where we don't need to worry about overflows: READ_LEB128 (len, p, end); if (len > (size_t) (end - p)) goto error_return; I'll note that this check does do things the right way: READ_LEB128 (symcount, p, end); /* Sanity check: each symbol has at least two bytes. */ if (symcount > payload_size / 2) return FALSE; "symcount * 2 > payload_size" would be wrong since the multiply could overflow. * wasm-module.c (wasm_scan_name_function_section): Formatting.

This changes the fix to PR 25210 by removing the ELF class change. As it turns out the correct change was only the change in compress.c. Everything else is unneeded and setting the elf class is making the linker behave very oddly under LTO. The first stub is correctly written out but for the rest the suddenly don't have a pointer to the stub section anymore. This caused SPEC to fail as the program would branch to the stub and it wouldn't be filled in.
