Alan Modra	ca0694adf6	Don't create .eh_frame_hdr on shared lib bfd If no object files have .eh_frame, but some shared library does, then ld creates a .eh_frame_hdr section using the shared library bfd. This is silly since shared library .eh_frame sections don't contribute to the output .eh_frame and thus no .eh_frame_hdr is needed. Also, the bfd section list and count is cleared for shared libraries, and a zero section count used as a flag in lang_check to omit a call to bfd_merge_private_bfd_data for shared libraries. If we create a section on a shared lib bfd then ld will wrongly attempt to merge the shared library private bfd data.

Andrew Burgess	9d7b48dc6e	AVR/ld: Propagate link-relax elf header flag correctly. The AVR target has an elf header flag to indicate if an object was assembler ready for linker relaxation. If a partial link is performed then it is important that the link-relax flag in the output object is set correctly, otherwise, during the final link, we might try to perform linker relaxation on code that was not assembled suitably. As the link-relax elf header covers the entire object file we must be conservative when setting the flag in the output object, so, for a partial link, any input object that does not have the link-relax flag set will cause the output object to also not have the link-relax flag set. This conservative approach could be softened in future, we only need to disable the link relax flag if an input file is not marked link-relax ready, and the input file contains a relaxable section. However, I've left this optimisation for a later day. For the final link I've overloaded the use of the link-relax elf header flag, in a final executable, the flag now indicates if the executable was built with linker relaxation on or not. ld/ChangeLog: * emultempl/avrelf.em: Add include of elf/avr.h.

Andrew Burgess	eac7440d80	AVR: Only set link-relax elf flag when appropriate. The AVR target uses a bit in the elf header flags to indicate if the object was assembled ready for linker relaxation. Previously this flag was always set, even when the object was not assembled ready for linker relaxation.

Mihail-Marian Nistor	87186c6a5c	gdb/17394: cannot put breakpoint only in selected ASM file. This patch fixes a problem when trying to insert a breakpoint on a specific symbol defined in a specific file, eg: break foo.c:func This currently works for files in C/C++/Ada, etc, but doesn't always work for Asm files. Analysis of the problem showed that this related to a limitation in gas, which does not generate debug info for functions/ symbols. Thus, we have a symtab for the file ("info sources" shows the file), but it contains no symbols. When find_linespec_symbols is called in linespec_parse_basic, it calls find_function_symbols, which uses add_matching_symbols_to_info to collect all matching symbols. That function does [pardon any mangled formatting]: for (ix = 0; VEC_iterate (symtab_ptr, info->file_symtabs, ix, elt); ++ix) { if (elt == NULL) { iterate_over_all_matching_symtabs (info->state, name, VAR_DOMAIN, collect_symbols, info, pspace, 1); search_minsyms_for_name (info, name, pspace); } else if (pspace == NULL \|\| pspace == SYMTAB_PSPACE (elt)) { /* Program spaces that are executing startup should have been filtered out earlier. / gdb_assert (!SYMTAB_PSPACE (elt)->executing_startup); set_current_program_space (SYMTAB_PSPACE (elt)); iterate_over_file_blocks (elt, name, VAR_DOMAIN, collect_symbols, info); } } This iterates over the symtabs. In the failing use case, ELT is non-NULL (points to the symtab for the .s file), so it calls iterate_over_file_blocks. Herein is where the problem exists: it is assumed that if NAME exists, it must exist in the given symtab -- a reasonable assumption for "normal" (non-asm) cases. It never searches minimal symbols (or in the global default symtab). This patch fixes the problem by doing so. It is important to note that iterating over minsyms is fairly expensive, so this patch only adds that extra search if the language is language_asm and iterate_over_file_blocks returns no symbols. gdb/ChangeLog: 2014-12-20 Keith Seitz <keiths@redhat.com> Mihail-Marian Nistor <mihail.nistor@freescale.com> PR gdb/17394 linespec.c (struct collect_minsyms): Add new member `symtab'.

Yao Qi	1bab73830f	MIPS: Provide FPU info and decode FCSR in `info float' This patch is the V2. V1 can be found in https://sourceware.org/ml/gdb-patches/2012-05/msg00938.html V2 is to address Joel's comment <https://sourceware.org/ml/gdb-patches/2012-06/msg00289.html> about keeping dumping floating point registers. Additionally, command 'info float' prints bits on nan2008 and abs2008. ------------------------------------------------------------------ The change below provides a MIPS-specific handler for the: (gdb) info float command. It provides information about the FPU type available (if any), the FPU register width, and decodes the CP1 Floating Point Control and Status Register (FCSR): (gdb) print /x $fsr $1 = 0xff83ffff (gdb) info float fpu type: double-precision reg size: 32 bits cond : 0 1 2 3 4 5 6 7 cause : inexact uflow oflow div0 inval unimp mask : inexact uflow oflow div0 inval flags : inexact uflow oflow div0 inval rounding: -inf flush : zero One point to note about CP1.FCSR are the non-standard Flush-to-Nearest and Flush-Override bits. They are not a part of the MIPS architecture and take two positions reserved for an implementation-dependent use in the architecture. They are present in all the FPU implementations made by MIPS Technologies since the spin-off from SGI. I haven't been able to track down a single other MIPS FPU implementation that would make any use of these bits and they are required to be hardwired to zero by the architecture specification if unimplemented. Therefore I think it makes sense to report them in the current way. GDB has no guaranteed access to the CP0 Processor Identification (PRId) register to validate this feature properly and the ID information stored in the CP1 Floating Point Implementation Register (FIR) is from my experience not reliable enough (there's no Company ID available there for once unlike in CP0.PRId and Processor ID is not guaranteed to be unique). As a side note we should probably dump CP1.FIR information as well, as there's useful stuff indicating some FPU features there. That's material for another change however. gdb/ 2014-12-18 Nigel Stephens <nigel@mips.com> Maciej W. Rozycki <macro@codesourcery.com> * mips-tdep.c (print_fpu_flags): New function.

Yao Qi	cc86d1cb95	Refactor gdbarch method print_float_info This patch is to change print_float_info gdbarch method for the following two reasons, 1. we want to add a default implementation of print_float_info to dump the float pointer registers. It can be reused by backend to print something more than float point registers. 2. we want to simplify the caller of print_float_info, infcmd.c:print_float_info. gdb: 2014-12-18 Yao Qi <yao@codesourcery.com> * gdbarch.sh (print_float_info): Change its type from 'M' to 'm'. * gdbarch.c: Re-generated. * gdbarch.h: Likewise. * infcmd.c (default_print_float_info): New function. (print_float_info): Removed. Move code to default_print_float_info. (float_info): Adjust to call gdbarch_print_float_info. * inferior.h (default_print_float_info): Declare it.	12 years ago
Yao Qi	2ad47ec433	Remove h8300_print_float_info In infcmd.c:print_float_info, if the architecture doesn't have gdbarch method print_float_info implemented and doesn't float reggroup, GDB will prints "No floating-point info available for this processor." The h8300 port doesn't have float registers, and don't need to implement print_float_info. This patch is to remove it. gdb: 2014-12-18 Yao Qi <yao@codesourcery.com> * h8300-tdep.c (h8300_print_float_info): Remove. (h8300_gdbarch_init): Remove the call to set_gdbarch_print_float_info.	12 years ago
