From a6c1c03a440ec55e427844ba851eed1ea2c95c95 Mon Sep 17 00:00:00 2001 From: Andreas Jaeger Date: Wed, 15 Nov 2000 08:46:30 +0000 Subject: Update. 2000-11-15 Andreas Jaeger * elf/cache.c (struct cache_entry): Use uint64_t for hwcap. (print_entry): Likewise. (add_to_cache): Likewise. * elf/ldconfig.h (add_to_cache): Change prototype for hwcap change. * elf/ldconfig.c (struct lib_entry): Use uint64_t for hwcap. (path_hwcap): Likewise. (search_dir): Likewise. * sysdeps/generic/dl-cache.c (HWCAP_CHECK): Handle platform. * elf/cache.c (add_to_cache): Handle 64 bit hwcap entry. * sysdeps/unix/sysv/linux/sparc/sparc32/dl-procinfo.h (_dl_platform_string): New. (_DL_HWCAP_PLATFORM): New. (_dl_string_platform): New. * sysdeps/unix/sysv/linux/sparc/sparc64/dl-procinfo.h: Likewise. * sysdeps/generic/dl-procinfo.h (_DL_HWCAP_COUNT): New. (_dl_string_platform): New. (_DL_HWCAP_PLATFORM): New. (_dl_platform_string): New. * sysdeps/unix/sysv/linux/i386/dl-procinfo.h: Added x86 platform recognition. (_DL_HWCAP_COUNT): New. (_dl_string_platform): New. (_DL_HWCAP_PLATFORM): New. (_dl_platform_string): New. --- elf/ldconfig.c | 35 ++++++++++++++++++++++------------- 1 file changed, 22 insertions(+), 13 deletions(-) (limited to 'elf/ldconfig.c') diff --git a/elf/ldconfig.c b/elf/ldconfig.c index 8b6a3d478d..068f43e1b9 100644 --- a/elf/ldconfig.c +++ b/elf/ldconfig.c @@ -28,6 +28,7 @@ #include #include #include +#include #include #include #include @@ -53,7 +54,7 @@ struct lib_entry { int flags; - unsigned long int hwcap; + uint64_t hwcap; char *lib; char *path; }; @@ -148,25 +149,31 @@ static struct argp argp = options, parse_opt, NULL, doc, NULL, NULL, NULL }; -/* Check if string corresponds to an important hardware capability. */ +/* Check if string corresponds to an important hardware capability or + a platform. */ static int -is_hwcap (const char *name) +is_hwcap_platform (const char *name) { int hwcap_idx = _dl_string_hwcap (name); if (hwcap_idx != -1 && ((1 << hwcap_idx) & HWCAP_IMPORTANT)) return 1; + + hwcap_idx = _dl_string_platform (name); + if (hwcap_idx != -1) + return 1; + return 0; } -/* Get hwcap encoding of path. */ -static unsigned long int +/* Get hwcap (including platform) encoding of path. */ +static uint64_t path_hwcap (const char *path) { char *str = xstrdup (path); char *ptr; - unsigned long int hwcap = 0; - unsigned long int h; + uint64_t hwcap = 0; + uint64_t h; size_t len; @@ -182,11 +189,13 @@ path_hwcap (const char *path) if (ptr == NULL) break; - h = _dl_string_hwcap (ptr+1); + h = _dl_string_hwcap (ptr + 1); + if (h == -1) + h = _dl_string_platform (ptr + 1); if (h == -1) break; - hwcap += 1 << h; + hwcap += 1ULL << h; /* Search the next part of the path. */ *ptr = '\0'; @@ -576,7 +585,7 @@ search_dir (const struct dir_entry *entry) struct dlib_entry *dlib_ptr; struct stat64 stat_buf; int is_link; - unsigned long int hwcap = path_hwcap (entry->path); + uint64_t hwcap = path_hwcap (entry->path); file_name_len = PATH_MAX; file_name = alloca (file_name_len); @@ -586,7 +595,7 @@ search_dir (const struct dir_entry *entry) if (opt_verbose) { if (hwcap != 0) - printf ("%s: (hwcap: 0x%lx)\n", entry->path, hwcap); + printf ("%s: (hwcap: 0x%Lx)\n", entry->path, hwcap); else printf ("%s:\n", entry->path); } @@ -630,7 +639,7 @@ search_dir (const struct dir_entry *entry) if (((strncmp (direntry->d_name, "lib", 3) != 0 && strncmp (direntry->d_name, "ld-", 3) != 0) || strstr (direntry->d_name, ".so") == NULL) - && !is_hwcap (direntry->d_name)) + && !is_hwcap_platform (direntry->d_name)) continue; len = strlen (entry->path) + strlen (direntry->d_name); if (len > file_name_len) @@ -662,7 +671,7 @@ search_dir (const struct dir_entry *entry) continue; } - if (S_ISDIR (stat_buf.st_mode) && is_hwcap (direntry->d_name)) + if (S_ISDIR (stat_buf.st_mode) && is_hwcap_platform (direntry->d_name)) { /* Handle subdirectory later. */ struct dir_entry *new_entry; -- cgit v1.2.3
