[PATCH] xtensa: fix __sigsetjmp call12 case
by Max Filippov 01 Apr '16

01 Apr '16

Register window saving loop in __sigsetjmp incorrectly calculates offset in the jmp_buf in case it was called with call12. The bug was introduced in commit f4b1b7ade7971141 "xtensa: fix setjmp that didn't save all registers correctly".

[PATCH] bits/byteswap-common.h: import recent headers from glibc
by Anthony G. Basile 01 Apr '16

01 Apr '16

From: "Anthony G. Basile" <blueness(a)gentoo.org> On systems where uClibc doesn't provide an arch specific byteswap.h, we fall back on bits/byteswap-common.h. However, there is a bug in this header in the __bswap_constant_64(x) macro. If, for example, a double is passed, we get 'invalid operands to binary &' in which we mismatch a 'double' and 'long long unsigned int'. The newer glibc headers fix this and so we import them. Also, since the inclusion of byteswap.h is not appropriate for assembly code, we guard a portion of endian.h which uses byteswap.h from inclusion in any assembly. This is needed, for example, for f2fs-tools 1.6.0 on 32-bit big endian PowerPC. Signed-off-by: Anthony G.

Provide an alias to _obstack_free?
by Alexey Neyman 31 Mar '16

31 Mar '16

Hi, GDB 7.11 does not build if compiled against uclibc-ng (1.0.12 was used, but the problematic code exists in 1.0.13 as well). The reason is that GDB release includes its own obstack implementation, but elides the code if <gnu-versions.h> declares a compatible obstack implementation in libc. uclibc-ng does claim compatible obstack interface (GDB expects version 2, but accepts version 1 if sizeof(int) == sizeof(size_t)), however, uclibc-ng does not provide the _obstack_free symbol that is a part of the interface (glibc does provide this symbol). This later causes a link failure. The attached patch makes uclibc-ng enables an alias _obstack_free -> obstack_free. Signed-off-by: Alexey Neyman <stilor(a)att.net> Regards, Alexey.

[PATCH] arm: simplify handling of Thumb related options
by Thomas Petazzoni 31 Mar '16

31 Mar '16

Currently, the Thumb support on ARM has three related Config.in options, which are not trivial for users to understand, and are in fact not needed: - The USE_BX option is not needed: knowing whether BX is available or not is easy. If you have an ARM > v4 or ARMv4T, then BX is available, otherwise it's not. This is the logic used in glibc. - The USE_LDREXSTREX option is not needed: whenever Thumb2 is available, ldrex/strex are available, so we can simply rely on __thumb2__ to determine whether ldrex/strex should be used, without requiring a Config.in option. - Once USE_BX and USE_LDREXSTREX are removed, the only thing left that COMPILE_IN_THUMB does is to set -mthumb. This makes the option unnecessary, as on ARM at least, the user is already supposed to pass -march=<foo> or other compiler options tuning the library for a specific ARM variant. There is no reason to do otherwise for Thumb, which allows to get rid of the COMPILE_IN_THUMB option.
