2018-02-09[IEPM] Introduce inline entry point markersAlexandre Oliva2-0/+3
Output DW_AT_entry_pc based on markers. Introduce DW_AT_GNU_entry_view as a DWARF extension. If views are enabled are we're not in strict compliance mode, output DW_AT_GNU_entry_view if it might be nonzero.

2018-02-09[LVU] Introduce location viewsAlexandre Oliva3-0/+16
This patch introduces an option to enable the generation of location views along with location lists. The exact format depends on the DWARF version: it can be a separate attribute (DW_AT_GNU_locviews) or (DW_LLE_view_pair) entries in DWARF5+ loclists. Line number tables are also affected. If the assembler is found, at compiler build time, to support .loc views, we use them and assembler-computed view labels, otherwise we output compiler-generated line number programs with conservatively-computed view labels. In either case, we output view information next to line number changes when verbose assembly output is requested. This patch requires an LVU patch that modifies the exported API of final_scan_insn. It also expects the entire SFN patchset to be installed first, although SFN is not a requirement for LVU. for include/ChangeLog * dwarf2.def (DW_AT_GNU_locviews): New. * dwarf2.h (enum dwarf_location_list_entry_type): Add DW_LLE_GNU_view_pair.

2017-11-10Add plugin API for processing plugin-added input files.Stephen Crane2-1/+22
Gold plugins may wish to further process an input file added by a plugin. For example, the plugin may need to assign a unique segment for sections in a plugin-generated input file. This patch adds a plugin callback that the linker will call when reading symbols from a new input file added after the all_symbols_read event (i.e. an input file added by a plugin). 2017-11-10 Stephen Crane <sjc@immunant.com> * plugin-api.h: Add plugin API for processing plugin-added input files.

2017-09-15[include] Add macro DISABLE_COPY_AND_ASSIGNYao Qi2-0/+31
We have many classes that copy cotr and assignment operator are deleted in different projects, gcc, gdb and gold. So this patch adds a macro to do this, and replace these existing mechanical code with macro DISABLE_COPY_AND_ASSIGN. The patch was posted in gdb-patches, https://sourceware.org/ml/gdb-patches/2017-07/msg00254.html but we think it is better to put this macro in include/ansidecl.h so that other projects can use it too. include: 2017-09-15 Yao Qi <yao.qi@linaro.org> Pedro Alves <palves@redhat.com> * ansidecl.h (DISABLE_COPY_AND_ASSIGN): New macro.

2017-09-12Add DW_CFA_AARCH64_negate_ra_state to dwarf2.def/h and dwarfnames.cJiong Wang3-0/+8
A new vendor CFA DW_CFA_AARCH64_negate_ra_state was introduced for ARMv8.3-A return address signing, it is multiplexing DW_CFA_GNU_window_save in CFA vendor extension space. This patch adds necessary code to make it available to external, the GDB patch (https://sourceware.org/ml/gdb-patches/2017-08/msg00215.html) is intended to use it. A new DW_CFA_DUP for it is added in dwarf2.def. The use of DW_CFA_DUP is to avoid duplicated case value issue when included in libiberty/dwarfnames. Native x86 builds OK to make sure no macro expanding errors.
