On other architectures crtbrand.c is included from crt1.c, but that's not a C source code file on ia64. Instead it is compiled separately and included in crt1.o using incremental linking.

| | | | | | | | | | | | | | | | | strptime(3) confused July with June with the fr_FR locale. When parsing the month "juillet" (abbr "jul"), %B recognized it as "juin" (abbr "jui") because the full name of the month names is checked at the same time as the abbrevation. The new behaviour checks the full names first before checking the abbrevation names. PR: kern/141939 Submitted by: Denis Chatelain <denis@tikuts.com> Notes: svn path=/stable/7/; revision=214080

* MFC r212373:Kai Wang2010-10-101-11/+6
| | | | | | | | | | | | | | | | libelf is overly strict about the type and alignment of Elf_Data objects inside one ELF section, which prevents the creation of a ELF section with mixed data types. For example, gcc LTO use libelf to create a .gnu_lto_XXX section that contains integers and a string table, which doesn't work with our libelf implementation. The changes made in this commit include: * Allow Elf_Data type to be different than section type. * Relax Elf_Data alignment check. * Align each Elf_Data by their own alignment instead of section alignment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Sync. printf() of libstand(3) with sys/kern/subr_prf.c. CVS r1.94 jhb: Cast the integer read as the first argument for %b to an unsigned integer so it's value is not sign extended when assigned to the uintmax_t variable used internally by printf. For example, if bit 31 is set in the cpuid feature word, then %b would print out the initial value as a 16 character hexadecimal value. Now it only prints out an 8 character value. CVS r1.109 njl: Add support for 'h' and 'hh' modifiers for printf(9). CVS r1.117 phk: If we ignore an unknown % sequence, we must stop interpreting the remaining % arguments because the varargs are now out of sync and there is a risk that we might for instance dereference an integer in a %s argument. SVN r209836 jkim: Implement optional 'precision' for numbers. Previously, it was parsed but ignored. Some third-party modules (e.g., ACPICA) prefer this format over zero padding flag '0'.

* MFC r206760: getcwd(3): Clarify that EACCES may or may not be checked.Jilles Tjoelker2010-05-051-3/+11
| | | | | | | | | | | | | | | | | | POSIX permits but does not require checking access on the current and parent directories. Because various programs do not like it if getcwd(3) fails, it seems best to avoid checking access as much as possible. There are various reports in GNATS about this (search for getcwd). Our getcwd(3) implementation first queries the kernel for the pathname directly, which does not check any permissions but sometimes fails, and then falls back to reading all parent directories for the names.
