2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-10-25[gdb/testsuite] Handle missing .note.GNU-stackTom de Vries1-0/+1
On openSUSE Tumbleweed I run into this for the dwarf assembly test-cases, and some hardcoded assembly test-cases: ... Running gdb.dwarf2/fission-absolute-dwo.exp ... gdb compile failed, ld: warning: fission-absolute-dwo.o: \ missing .note.GNU-stack section implies executable stack ld: NOTE: This behaviour is deprecated and will be removed in a future \ version of the linker === gdb Summary === # of untested testcases 1 ... Fix the dwarf assembly test-cases by adding the missing .note.GNU-stack in proc Dwarf::assemble. Fix the hard-coded test-cases using this command: ... $ for f in $(find gdb/testsuite/gdb.* -name *.S); do if ! grep -q note.GNU-stack $f; then echo -e "\t.section\t.note.GNU-stack,\"\",@progbits" >> $f; fi; done ... Likewise for .s files, and gdb/testsuite/lib/my-syscalls.S. The idiom for arm seems to be to use %progbits instead, see commit 9a5911c08be ("gdb/testsuite/gdb.dwarf2: Replace @ with % for ARM compatability"), so hand-edit gdb/testsuite/gdb.arch/arm-disp-step.S to use %progbits instead. Note that dwarf assembly testcases use %progbits as decided by proc _section. Tested on x86_64-linux. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29674
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1
This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.

gdb/ChangeLog: Update copyright year range in all GDB files.
2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

2015-11-07testsuite: Define and use gdb_target_symbol_prefix_flags_asm.Kevin Buettner1-4/+13
Some of the source code for the test cases in the GDB testsuite reside in .S files containing assembly code. These files typically define a symbol - such as main - which may, depending on the target, require a prefix such as underscore. For example, gdb.dwarf2/dw-compdir-oldgcc.S defines the symbol main: main: .globl main Some targets, such as rx-elf, require main to have an underscore prefix. (If it doesn't, a linker error results due to not being able to find _main required by crt0.o.) So, instead, the above should look like this for rx-elf and other targets with this same requirement: _main: .globl _main This patch defines a new tcl proc in lib/gdb named gdb_target_symbol_prefix_flags_asm. This proc returns a string which will - assuming everything else is wired up correctly - cause -DSYMBOL_PREFIX=_ to be passed on the command line to the compiler. The test cases are augmented with a macro definition for SYMBOL as follows: #define CONCAT1(a, b) CONCAT2(a, b) #define CONCAT2(a, b) a ## b #ifdef SYMBOL_PREFIX # define SYMBOL(str) CONCAT1(SYMBOL_PREFIX, str) #else # define SYMBOL(str) str #endif Symbols, such as main shown in the example earlier are then wrapped with SYMBOL like this: SYMBOL(main): .globl SYMBOL(main) The net effect will be to add a prefix for those targets which need it and add no prefix for those targets which do not. It should be noted that there was already a proc in lib/gdb.exp called gdb_target_symbol_prefix_flags. It still exists, but has been significantly rewritten. (There is only one small difference between the two versions.) That proc used to explicitly list targets which were known to require an underscore prefix. This is no longer done; the recently added proc, gdb_target_symbol_prefix, is now invoked to dynamically discover whether or not a prefix is required for that particular target. The difference between gdb_target_symbol_prefix_flags_asm and gdb_target_symbol_prefix_flags is that the former returns a bare prefix while the latter returns the prefix enclosed in double quotes. I.e. assuming that the discovered prefix is underscore, gdb_target_symbol_prefix_flags_asm returns: additional_flags=-DSYMBOL_PREFIX=_ while gdb_target_symbol_prefix_flags returns: additional_flags=-DSYMBOL_PREFIX="_" The double-quoted version is not suitable for using with .S files containing assembly code; there is no way to strip the double quotes using C preprocessor constructs. It would be possible to use the bare (non double quoted) version in C source code. However, the supporting macros become more complicated and therefore more difficult to maintain. gdb/testsuite/ChangeLog: * lib/gdb (gdb_target_symbol_prefix_flags_asm): New proc. (gdb_target_symbol_prefix_flags): Define in terms of _asm version. * gdb.arch/i386-float.exp, gdb.arch/i386-permbkpt.exp, gdb.dwarf2/dw2-canonicalize-type.exp, gdb.dwarf2/dw2-compdir-oldgcc.exp, gdb.dwarf2/dw2-minsym-in-cu.exp, gdb.dwarf2/dw2-op-stack-value.exp, gdb.dwarf2/dw2-unresolved.exp, gdb.dwarf2/fission-reread.exp, gdb.dwarf2/pr13961.exp: Use flags provided by gdb_target_symbol_prefix_flags_asm. * gdb.dwarf2/dw2-canonicalize-type.S, gdb.dwarf2/dw2-compdir-oldgcc.S, testsuite/gdb.dwarf2/dw2-minsym-in-cu.S, testsuite/gdb.dwarf2/dw2-unresolved-main.c, testsuite/gdb.dwarf2/dw2-unresolved.S, gdb.dwarf2/fission-reread.S, gdb.dwarf2/pr13961.S: Define and use SYMBOL macro (and supporting macros where needed). Use this macro for symbols which require the prefix provided by SYMBOL_PREFIX.
