2011-06-14config: Fix passing defconfig argsBernhard Reutner-Fischer
Don't rely on argument-shuffling but use correct arguments in the first place. In bug#3589 Thomas Suckow writes: The modified kconfig defines -D to be the same function as -d. In addition -d does not take an argument and Config.in should be passed as a non-option argument. The existing argument order appears to work on distributions such as Fedora but chokes on Cygwin (newlib?). Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2011-06-14libdl: search for ELF_RTYPE_CLASS_DLSYM in dlsym()Bernhard Reutner-Fischer
On FDPIC platforms, functions are passed by function descriptor, not by pointers. If you don't specify ELF_RTYPE_CLASS_DLSYM when calling _dl_find_hash() the return value from dlsym() will be a pointer not a function descriptor, crashing the program. The bug was introduced when TLS support was added in 534661b91c98492995274c364c8177c45efc63db Closes bug#3433 Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

in bug 3637 Andrey Kovalev aka pxe.ru writes: getaddrinfo does NOT add domain to query when receive SERVFAIL RFC1035 7.2 suggests that - If a resolver gets a server error or other bizarre response from a name server, it should remove it from SLIST, and may wish to schedule an immediate transmission to the next candidate server address.

2011-06-11Rules.mak: Rearrange appending UCLIBC_EXTRA_CFLAGS to CFLAGSKhem Raj
UCLIBC_EXTRA_CFLAGS is currently added before the OPTIMIZATION flags and OPTIMIZATION is chosen to be Os by default. But in OE we pass the optimisation flags through UCLIBC_EXTRA_CFLAGS but they are not effective since -Os is specified at last. So we need to change the order of these option flags Signed-off-by: Khem Raj <raj.khem@gmail.com>
2011-06-11ARM: remove EABI/OABI selectionYann E. MORIN
Rely on the compiler to be properly setup for the default ABI. When installing-headers, there are two cases: - NPTL: no issue, a cross-compiler is already expected - LinuxThreads: no issue, EABI/OABI has no impact on installed headers. Signed-off-by: "Yann E.

2011-06-11ARM: remove sub-arch/variants selection from menuconfigYann E. MORIN
Rely on the compiler to be correctly set up to generate appropriate code for the target variant. This exposes the Thumb option, as it is no longer auto-selected. The "Use BX" no longer depends on supported CPU to be selected, so it now defaults to 'n' as it shall work by default on CPUs that do not have BX. Signed-off-by: "Yann E.

2011-06-11ARM: introduce blind options to select & force THUMB modeYann E. MORIN
Add three new blind options to set use of Thumb mode: - COMPILE_IN_THUMB_MODE - if set, CFLAGS will contain -mthumb - if unset, the compiler's default is used - HAS_THUMB - CPUS with Thumb instruction set can select this - use of BX depends on this - FORCE_THUMB - CPUs that are Thumb-only must select this - this selects: HAS_THUMB, COMPILE_IN_THUMB_MODE and USE_BX Also, remove leading space in Rules.mak.

2011-06-11ARM: reorder "Use BX" optionYann E. MORIN

2011-05-27Correct a bug when remapping textrel segments on nommuAlan Davis
From: Alan Davis <adavis@ti.com> On C6X, when trying to execute a program that has a textrel DSO, it fails to load. The telltale line in the LD_DEBUG output is: _dl_get_ready_to_run:779: file=''; needed by './a.out' The corresponding DT_NEEDED entry has 'libc.so.0', but here the filename is empty. This is what is happening in _dl_elf_shared_library(): First, map all segments according to their permissions. Text gets initially mapped read-only. Then, parse the dynamic information. The dynamic table is in RW but some of the tags may point to RO. For example, DT_NEEDED points to a string in .dynstr which is in RO. These pointers get computed according to the loadmap from the original mapping. Then, in response to a DT_TEXTREL tag, the RO segment gets remapped, thereby invaliding anything that points to it, in particular certain dynamic tags such as DT_NEEDED. The following patch re-parses the dynamic info after the remapping so as to re-compute any invalid pointers.
