From: John Baldwin Date: Fri, 23 Sep 2022 22:36:10 +0000 (-0700) Subject: Support AT_USRSTACKBASE and AT_USRSTACKLIM. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4f60f82104e428ba23cf7c82cde7ea536af092fd;p=binutils-gdb.git Support AT_USRSTACKBASE and AT_USRSTACKLIM. FreeBSD's kernel has recently added two new ELF auxiliary vector entries to describe the location of the user stack for the initial thread in a process. This change displays the proper name and description of these entries in 'info auxv'. --- diff --git a/gdb/fbsd-tdep.c b/gdb/fbsd-tdep.c index 40370100c0f..309777c55f2 100644 --- a/gdb/fbsd-tdep.c +++ b/gdb/fbsd-tdep.c @@ -1571,6 +1571,8 @@ fbsd_print_auxv_entry (struct gdbarch *gdbarch, struct ui_file *file, TAG (PS_STRINGS, _("Pointer to ps_strings"), AUXV_FORMAT_HEX); TAG (FXRNG, _("Pointer to root RNG seed version"), AUXV_FORMAT_HEX); TAG (KPRELOAD, _("Base address of vDSO"), AUXV_FORMAT_HEX); + TAG (USRSTACKBASE, _("Top of user stack"), AUXV_FORMAT_HEX); + TAG (USRSTACKLIM, _("Grow limit of user stack"), AUXV_FORMAT_HEX); } fprint_auxv_entry (file, name, description, format, type, val); diff --git a/include/elf/common.h b/include/elf/common.h index ebcd8f9e82c..287526d74ed 100644 --- a/include/elf/common.h +++ b/include/elf/common.h @@ -1405,6 +1405,8 @@ #define AT_FREEBSD_PS_STRINGS 32 /* struct ps_strings. */ #define AT_FREEBSD_FXRNG 33 /* Pointer to root RNG seed version. */ #define AT_FREEBSD_KPRELOAD 34 /* Base of vdso. */ +#define AT_FREEBSD_USRSTACKBASE 35 /* Top of user stack. */ +#define AT_FREEBSD_USRSTACKLIM 36 /* Grow limit of user stack. */ #define AT_SUN_UID 2000 /* Effective user ID. */ #define AT_SUN_RUID 2001 /* Real user ID. */
