2015-10-29Re: Orphan output section with multiple input sectionsAlan Modra7-18/+76
The last patch missed handling the case where the ideal place to put an orphan was after a non-existent output section statement, as can happen when not using the builtin linker scripts.

2015-10-28Pass noaliases_p to aarch64_decode_insnYao Qi6-8/+27
Nowadays aarch64_decode_insn is a public interface used by both opcodes and gdb. However, its behaviour relies on a global variable no_aliases, which isn't a good practise. On the other hand, In default, no_aliases is zero, but in GDB, we do want no alias when decoding instructions for prologue analysis (patches to be posted), so that we can handle both instructions "add" and "mov" (an alias of "add") as "add". The code in GDB can be simplified. This patch adds a new argument in aarch64_decode_insn, and pass no_aliases to it. In GDB side, always pass 1 to it. include/opcode: 2015-10-28 Yao Qi <yao.qi@linaro.org> * aarch64.h (aarch64_decode_insn): Update declaration. opcodes: 2015-10-28 Yao Qi <yao.qi@linaro.org> * aarch64-dis.c (aarch64_decode_insn): Add one argument noaliases_p.

Fixes a set of errors like: ../../src/gdb/symfile-debug.c: In function ‘int debug_qf_map_symtabs_matching_filename(objfile*, const char*, const char*, int (*)(symtab*, void*), void*)’: ../../src/gdb/symfile-debug.c:137:39: error: invalid conversion from ‘int (*)(symtab*, void*)’ to ‘const void*’ [-fpermissive] host_address_to_string (callback), ^ Note this has to work with data and function pointers. In C++11 we may perhaps do something a bit safer, but we're not there yet, and I don't think it really matters. For now just always do a simple C-style cast in host_address_to_string itself. No point in adding a void * cast to each and every caller. gdb/ChangeLog: 2015-10-27 Pedro Alves <palves@redhat.com> * common/print-utils.c (host_address_to_string): Rename to ...

2015-10-27target_read_memory&co: no longer return target_xfer_statusPedro Alves8-49/+72
Years ago, these functions used to return errno/EIO. Later, through a series of changes that intended to remove native/remote differences, they ended up returning a target_xfer_status in disguise. Unlike target_xfer_partial&co, the point of target_read_memory&co is to either fully succeed or fail. On error, they always return TARGET_XFER_E_IO. So there's no real point in casting the return of target_read_memory to a target_xfer_status to pass it to memory_error. Instead, it results in clearer code to simply decouple target_read_memory&co's return from target_xfer_status. This fixes build errors like this in C++ mode: ../../src/gdb/corefile.c: In function ‘void read_stack(CORE_ADDR, gdb_byte*, ssize_t)’: ../../src/gdb/corefile.c:276:34: error: invalid conversion from ‘int’ to ‘target_xfer_status’ [-fpermissive] memory_error (status, memaddr); ^ ../../src/gdb/corefile.c:216:1: error: initializing argument 1 of ‘void memory_error(target_xfer_status, CORE_ADDR)’ [-fpermissive] gdb/ChangeLog: 2015-10-27 Pedro Alves <palves@redhat.com> * alpha-tdep.c (alpha_read_insn): Always pass TARGET_XFER_E_IO to memory_error.

2015-10-27source.c:openp: save/restore errnoPedro Alves2-0/+12
openp's return is documented as: ~~~ If a file is found, return the descriptor. Otherwise, return -1, with errno set for the last name we tried to open. */ ~~~ By inspection, I noticed that there are function calls after the ones that first set errno, and those may clobber errno. It's safer to save errno when see an open fail, and restore it on exit.

2015-10-27Evaluate __start_* and __stop_* symbol PROVIDE expressions earlyAlan Modra3-9/+32
Makes these symbols defined before bfd_elf_size_dynamic_sections, to avoid horrible hacks elsewhere. The exp_fold_tree undefweak change is necessary to define undefweak symbols early too. The comment was wrong. PROVIDE in fact defines undefweak symbols, via bfd_elf_record_link_assignment.
