2018-06-28T08:22:35+00:00

Refresh 0014-Define-GLIBC_DYNAMIC_LINKER-and-UCLIBC_DYNAMIC_LINKE.patch to also define GLIBC_DYNAMIC_LINKER relative to SYSTEMLIBS_DIR on riscv. (From OE-Core rev: 12e859dfb70f8aae40edfd88b143b6c771f4e1a6) Signed-off-by: Ricardo Salveti Signed-off-by: Richard Purdie

gcc-8: Enable fp arch extention when fpu is available

2018-06-21T08:34:40+00:00

This is especially needed when defaulting to hard-float ABI Fixes errors e.g. cc1: error: -mfloat-abi=hard: selected processor lacks an FPU Fixes [YOCTO #12795] (From OE-Core rev: 85981cbbf0ce48a6d82bc39248afa9540ca858d8) Signed-off-by: Khem Raj Cc: Ross Burton Signed-off-by: Richard Purdie

gcc-target.inc: configure gcc for armv7ve targets to default to armv7ve

2018-06-18T10:07:58+00:00

Originally these ARM specific EXTRA_OECONF options were applied to both gcc for the target and gcc-cross. That lead to a compromise being made: gcc on the target was configured to default to an ARM architecture which was at least compatible with the target (but not necessarily an exact match) and gcc-cross was configured default to armv7a for both armv7a and armv7ve (to avoid gcc-cross rebuilds when switching between the two). However, when these ARM specific EXTRA_OECONF options were moved from gcc-configure-common.inc into gcc-target.inc (ie they were made to apply only to gcc on the target) the compromise no longer needed to be made. http://git.openembedded.org/openembedded-core/commit/?id=851937dde81de2a9ef54c5f19a78fb12fb82afd4 (From OE-Core rev: 3c368282741e9de1f96988e127b86a6a01b6a26f) Signed-off-by: Andre McCurdy Signed-off-by: Richard Purdie

gcc8: drop stray uClibc specific patch

2018-06-18T10:07:57+00:00

The patch was previously removed for gcc7 but came back with gcc8. http://git.openembedded.org/openembedded-core/commit/?id=f71bc69e5b7581c53071055b694bb0dbfe4b4a87 (From OE-Core rev: 5f1b9128bd8693b2309c07cfc2de7b8f77c34da1) Signed-off-by: Andre McCurdy Signed-off-by: Khem Raj Signed-off-by: Richard Purdie

gcc-8: enable build-id in gcc-cross-initial

2018-06-15T16:56:24+00:00

Apply patch from Taras Kondratiuk to gcc 8.x too. Normal gcc-cross has build-id feature enabled by default, so most of target binaries has build-id. But libc (glibc, musl) doesn't have build-id, because it is built with gcc-cross-initial. Build-id is a useful feature, so enable it for gcc-cross-initial too.

tclibc-newlib: Adds a new TCLIBC variant to build with newlib as C library

2018-06-15T16:56:24+00:00

This patch adds the posibility to build using TCLIBC=newlib. It allows users to build baremetal applications with the use of a C library. Newlib is a lightweight C library meant to be used on embedded systems, it is meant to be easily portable for new platforms and to provide basic functionality on them, by design, it provides stubs for some of these core functions declared as weak, so they can be built correctly and then linked against some other library which provides specifics about the platform being used if need be, libgloss takes care of these in some cases, but it can also be extended, this patch also allows the user to easily add other libraries to it by adding them to NEWLIB_EXTENDED for this specific reason.

newlib: Adds newlib and libgloss recipes

2018-06-15T16:56:24+00:00

Newlib is a C library that is intended to be used on embedded systems. It is a conglomeration of several library parts, all under free software licenses that make them easily usable on embedded products. Newlib provides a C library alternative that can run on baremetal, mainly for resource constrained devices. Libgloss is the BSP part of the C library, which can be easily modified to port for new hardware platforms.
