gdb: properly pass the PATH when building gdb for the host

2012-11-28T19:35:57Z

When building gdb for the host, we properly pass the PATH (through HOST_CONFIGURE_OPTS) during the configure step, but we forget to do so for the compilation step. The result of this is that when the Crosstool-NG backend is used, gawk is built and installed in $(HOST_DIR), as a dependency of the crosstool-ng package. Then, the host gdb configure script detects this gawk binary ($(HOST_DIR) is in the PATH), and assumes gawk is available. Unfortunately, during the compilation step, it fails to find the expected gawk binary, because $(HOST_DIR) is no longer in the PATH. This causes the following build failure: http://autobuild.buildroot.org/results/067d0c2ea01673ba98ec11de2426f1ab92dac800/build-end.log In order to fix this, we simply call the compilation step of gdb for the host with $(HOST_MAKE_ENV), as it should have been done from the beginning.

xtensa: fix target gdb build and 64-bit host side gdb

2012-11-21T10:14:24Z

Fix build breakage, use the version of the ptrace header file in asm instead of sys. Also, fix GDB running on 64 bit hosts. GDB was using unsigned long for 32-bit registers, but unsigned long is 64 bit on 64-bit hosts. Signed-off-by: Chris Zankel Signed-off-by: Peter Korsgaard

xtensa: use uppercase for configurations and modified overlay structure

2012-11-21T10:08:50Z

Except for architecture and processor names, buildroot uses capitalized configuration names, so change the macro names for xtensa to follow that standard. Change the overlay file to have a subdirectory for each component (gdb, binutils, gcc, etc.) to make it more future-prove. Signed-off-by: Chris Zankel Signed-off-by: Peter Korsgaard

toolchain/gdb: disable support of full gdb on target for blackfin

2012-11-15T23:28:40Z

There is no support in gdb 6.6 for the Blackfin architecture, so disallow this choice. This fixes the following build failure: http://autobuild.buildroot.org/results/e37db29810265a756833da163fda444d967d7874/build-end.log Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

xtensa: support configurable processor configurations

2012-11-15T15:39:48Z

Xtensa is a configurable processor architecture, which allows to define additional instructions and registers. The required variant specific information for the toolchain is delivered in an 'overlay' file, which needs to be 'untarred' to the corresponding directories after the source is installed and patched. This patch provides support for binutils, gcc, and gdb with a very limited changes to the build scripts. These additions are only executed for the Xtensa architecture and have no effect on other architectures. [Thomas: rebased on top of the 'arch: improve definition of gcc mtune, mcpu, etc.' patch, and changed 'Target ABI' to 'Target Architecture Variant'].

gdb: adjust behavior when thread debug is not available

2012-11-03T16:51:29Z

When an external toolchain without thread debug is used, the gdb package can be selected, but no version can be choosen, since none match any of the requirements. This leads Buildroot to try to build gdb for the target without a version being defined, as in the following build log: http://autobuild.buildroot.org/results/84e8fd2df0cc22448052a572c2e9a6e03dd137eb/build-end.log To fix this, we adjust the dependencies of the BR2_PACKAGE_GDB option so that the package as a whole is not selectable when the required conditions are not met. Basically, we have the choice of: * Having a toolchain that supports thread debugging, which is needed for gdb >= 7.x * Having BR2_DEPRECATED enabled, which allows gdb 6.8 to be selected, which doesn't require thread debugging * Using bfin, since this architectures has a special old gdb version Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

Remove the Xtensa architecture

2012-09-20T20:31:08Z

As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, the Xtensa architecture has been introduced in 2009 and never changed since its initial introduction. It requires some special handling that is a bit annoying, and despite our call to the initial developers, and the announcement of the deprecation of the architecture during the 2012.05, nothing has happened. Therefore, drop support for this architecture. Signed-off-by: Thomas Petazzoni Acked-by: me Signed-off-by: Peter Korsgaard
