2020-01-05gdb: use tui_set_layout not show_layout to fix window focusAndrew Burgess4-6/+18
When calling tui_add_win_to_layout, use tui_set_layout not show_layout so that window focus is correctly updated. If the focus is not correctly maintained then GDB can be crashed like this: start tui enable layout asm list SOME_FUNCTION At this point GDB will have "popped up" the source window to display SOME_FUNCTION. Previously no window would have focus at this point, and so if the user now does 'focus next' or 'focus prev', then GDB would crash. Calling tui_set_layout ensures that focus is correctly calculated as the source window is "popped up", and this fixes the issue. gdb/ChangeLog: * tui/tui-layout.c (tui_add_win_to_layout): Use tui_set_layout not show_layout. gdb/testsuite/ChangeLog: * gdb.tui/list.exp: Test 'focus next' after 'list main'.

2020-01-05libctf: Add configure check for asprintf (for MinGW)Eli Zaretskii4-2/+72
This commit fixes a compilation warning when compiling libctf on MinGW: libctf/ctf-dump.c:118:8: warning: implicit declaration of function 'asprintf'; did you mean 'vasprintf'? [-Wimplicit-function-declaration] if (asprintf (&bit, " %lx: [slice 0x%x:0x%x]", ^~~~~~~~ vasprintf MinGW doesn't provide that function, so we depend on the one provided by libiberty. However, the declaration is guarded by HAVE_DECL_ASPRINTF, which we do not have in libctf's config.h. libctf/ChangeLog: PR binutils/25155: * configure.ac: Add AC_CHECK_DECLS([asprintf]). * configure, config.h.in: Regenerate.

2020-01-02AArch64: Set the correct ELF class for AArch64 stubs (PR/25210)Tamar Christina6-1/+75
This fixes PR 25210 by specifying the the correct ELF class for AArch64 stubs. After doing this the stub section starts behaving like a normal object file loaded from disk. That is SEC_LINKER_CREATED causes us to have to write the section manually. This flag was added as a fix for PR 24753. I believe that fix to still be correct as linker created sections don't have a size on disk and it fixes the Arm bootstrap regression. But in this case specifying the correct section class also makes the stub section not be considered by compress.c. So I'm partially revert this change so that we don't have to manage the section manually as implied by SEC_LINKER_CREATED. bfd/ChangeLog: PR 25210 PR 24753 * elfnn-aarch64.c (_bfd_aarch64_create_stub_section): Set ELF class. ld/ChangeLog: PR 25210 PR 24753 * emultempl/aarch64elf.em (elf${ELFSIZE}_aarch64_add_stub_section): Remove SEC_LINKER_CREATED. * testsuite/ld-aarch64/aarch64-elf.exp: Add erratum835769-843419. * testsuite/ld-aarch64/erratum835769-843419.d: New test.
