* ARC: allow selection of MMU page sizeGravatar Alexey Brodkin2015-07-181-0/+38
| | | | | | | | | | | | | | | | | | Modern ARC cores (those sporting MMU of version 3 and 4) allow selection of different page sizes (4, 8 or 16 kB) during ASIC design creation. And it's important to build a toolchain with page size setting that matches hardware. Otherwise user-space applications will fail on execution due to unexpected data layout/alignment etc. [Thomas: slightly improve help text, fix indentation of help text.] Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Anton Kolesov <akolesov@synopsys.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Arnout Vandecappelle <arnout@mind.be> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

* arch: BINFMT_FLAT_SHARED is not really shared for buildroot purposesGravatar Sonic Zhang2015-03-301-1/+6
| | | | | | | | | | | | | | | | | | | | Although BINFMT_FLAT_SHARED is indeed a shared library format, it does not support dynamic library loading with dlopen(). So for buildroot purposes, BR2_STATIC_LIBS shouldn't be selected. As it happens, the compiler options that are added for BINFMT_FLAT_SHARED also make the compiler ignore the -static option, so we can simply force BR2_STATIC_LIBS and things work out perfectly. Therefore, remove the select of BR2_BINFMT_SUPPORTS_SHARED from BINFMT_FLAT_SHARED, which in turn makes sure that BR2_STATIC_LIBS is selected.

* Turn the static lib option into a choice with more optionsGravatar Thomas Petazzoni2014-12-121-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit turns the single static option into a choice, which offers various possibilities: 1. Build and use static libraries only; 2. Build both shared and static libraries, but use shared libraries; 3. Build and use shared libraries only. On most platforms, (2) is currently the default, and kept as the default in this commit. Of course, on certain platforms (Blackfin, m68k), only option (1) will be available. In addition to the introduction of the Config.in options, this commit also: * Removes the 'select BR2_STATIC_LIBS' from 'BR2_BINFMT_FLAT', since with the use of a choice, we are guaranteed that BR2_STATIC_LIBS will be selected when the binary format is BR2_BINFMT_FLAT, since BR2_STATIC_LIBS will be the only possible solution in the choice. * Changes package/Makefile.in to use the proper --{enable,disable}-{shared,static} options for autotools packages.

| | | | | | | | | | | | | | | | | | | Currently, the binary format choice is only shown for the Blackfin and m68k architectures, since we assume that all other architectures are using the ELF binary format. However, due to this, the BR2_BINFMT_ELF symbol is in fact not set to 'y' for those architectures that use the ELF format. This will be causing problems for the refactoring of the static/shared library support, as we will need to know if the binary format supports shared libraries or not. Therefore, we simply make the choice visible on all architectures, even if it means that on many architectures no other choice than ELF will be available.

* Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBSGravatar Thomas Petazzoni2014-12-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed from "prefer static libraries when possible" to "use only static libraries". The former semantic didn't make much sense, since the user had absolutely no control/idea of which package would use static libraries, and which packages would not. Therefore, for quite some time, we have been starting to enforce that BR2_PREFER_STATIC_LIB should really build everything with static libraries. As a consequence, this patch renames BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS, and adjust the Config.in option accordingly. This also helps preparing the addition of other options to select shared, shared+static or just static. Note that we have verified that this commit can be reproduced by simply doing a global rename of BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

* arch/Config.in.x86: drop BR2_x86_genericGravatar Peter Korsgaard2014-11-071-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fuzzy generic x86 variant doesn't make much sense in the context of Buildroot, and the recent change to use -march instead of -mtune broke it. From the GCC manual: https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/i386-and-x86-64-Options.html#i386-and-x86-64-Options: -mtune=cpu-type Tune to cpu-type everything applicable about the generated code, except for the ABI and the set of available instructions. While picking a specific cpu-type schedules things appropriately for that particular chip, the compiler does not generate any code that cannot run on the default machine type unless you use a -march=cpu-type option. For example, if GCC is configured for i686-pc-linux-gnu then -mtune=pentium4 generates code that is tuned for Pentium 4 but still runs on i686 machines. The choices for cpu-type are the same as for -march. In addition, -mtune supports 2 extra choices for cpu-type: ‘generic’ Produce code optimized for the most common IA32/AMD64/EM64T processors. If you know the CPU on which your code will run, then you should use the corresponding -mtune or -march option instead of -mtune=generic. But, if you do not know exactly what CPU users of your application will have, then you should use this option. As new processors are deployed in the marketplace, the behavior of this option will change. Therefore, if you upgrade to a newer version of GCC, code generation controlled by this option will change to reflect the processors that are most common at the time that version of GCC is released. There is no -march=generic option because -march indicates the instruction set the compiler can use, and there is no generic instruction set applicable to all processors. In contrast, -mtune indicates the processor (or, in this case, collection of processors) for which the code is optimized. Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

| | | | | | | | | | | | | | | | | | | | | | According to the gcc documentation for PowerPC options: '-mtune=CPU_TYPE' Set the instruction scheduling parameters for machine type CPU_TYPE, but do not set the architecture type, register usage, or choice of mnemonics, as '-mcpu=CPU_TYPE' would. The same values for CPU_TYPE are used for '-mtune' as for '-mcpu'. If both are specified, the code generated will use the architecture, registers, and mnemonics set by '-mcpu', but the scheduling parameters set by '-mtune'. In the case of Buildroot where we only target a specific system, using -mtune therefore doesn't make much sense, and using -mcpu would be more appropriate.

However, depending on the version of gcc, a given combination of (CPU, architecture) may not be the same. Since the architecture variant is implied by the CPU type, given the former is not necessary, and we can simply specify the latter. >From the gcc documentation: This specifies the name of the target ARM processor. GCC uses this name to derive the name of the target ARM architecture (as if specified by -march) and the ARM processor type for which to tune for performance (as if specified by -mtune). Where this option is used in conjunction with -march or -mtune, those options take precedence over the appropriate part of this option.

* arch/arm: do not distinguish revisions of ARM1136JF-SGravatar Thomas Petazzoni2014-11-071-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 88cf3bb91792c9c04586e14f293d89a6e0c13e1d ("arch/Config.in.arm: Use armv6k for arm1136jf-s rev1"), Benoît Thébaudeau added separate options for the revision 0 and revision 1 of the ARM1136JF-S processor, so that different -march values could be used (armv6j for revision 0, armv6k for revision 1). However, this is preventing the removal of the BR2_GCC_TARGET_ARCH option, which we need to do to give only the CPU type to gcc, and let it decide the architecture variant that matches. This is because this story of revision 0 vs. revision 1 is the only case where -mcpu doesn't fully define the CPU. Moreover, a quick test with gcc shows that -march=armv6j -mcpu=arm1136jf-s is accepted, while -march=armv6k -mcpu=arm1136jf-s makes gcc complain: " warning: switch -mcpu=arm1136jf-s conflicts with -march=armv6k switch". In addition, gcc 5 will apparently no longer allow to pass all of --with-arch, --with-cpu and --with-tune, so we will anyway have to rely only on one of them. As a consequence, this commit basically reverts 88cf3bb91792c9c04586e14f293d89a6e0c13e1d and provides only one option for ARM1136JF-S. If the two revisions are really different, then they should be supported in upstream gcc with different -mcpu values. Note that the removal of the two options should not break existing full .config, since the hidden option BR2_arm1136jf_s becomes again a visible option to select the CPU.

| | | | | | | | | | | | | | | | | | Due to a kconfig limitation, we can't select a no-prompt symbol that gets its dependencies by being conditionally re-defined in one or more if-blocks, like we currently do for BR2_ARCH_HAS_ATOMICS. As a workaround to this issue, we just redefine that symbol in the arc if-block, like we do for all other architectures, except that in the arc case, the default value is conditional.

| | | | | | | | | | Now that all architectures explicitly select this option when it makes sense, there is no need to have a default value. Signed-off-by: "Yann E.
