* Add support for Semihosting v2 support for ARM in libgloss.Tamar Christina2017-07-053-65/+231
| | | | | | | | | | Semihosting v2 changes are documented here: https://developer.arm.com/docs/100863/latest/ The biggest change is the addition of an extensions mechanism to add more extensions in the future. Signed-off-by: Tamar Christina <tamar.christina@arm.com>

| | | | | | | | | | | | | | | | | | libraries for Semihosting v2 for ARM. This uses the new recursive build target in multi-build.in The new spec files are: For AArch32/ARM (m for mixed mode): - rdimon-v2m.specs - aprofile-validation-v2m.specs - aprofile-ve-v2m.specs These spec files will be using the new libraries generated by multi-build.in.

* ARM/AArch64: Fix GetCmdLine semihosting directivesnewlib-snapshot-20170519Laurent ALFONSI2017-05-191-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When simulating arm code, the target program startup code (crt0) uses semihosting invocations to get the command line from the simulator. The simulator returns the command line and its size into the area passed in parameter. (ARM 32-bit specifications : http://infocenter.arm.com/help/topic/com.arm.doc.dui0058d/DUI0058.pdf chapter "5.4.19 SYS_GET_CMDLINE"). The memory area pointed by the semihosting register argument is located in .text section (usually not writtable (RX)). If we run this code on a simulator that respects this rights properties (qemu user-mode for instance), the command line will not be written to the .text program memory, in particular the length of the string. The program runs with an empty command line. This problem hasn't been seen earlier probably because qemu user-mode is not so much used, but this can happen with another simulator that refuse to write in a read-only segment. With this modification, the command line can be correctly passed to the target program. Changes: - libgloss/arm/crt0.S : Arguments passed to the AngelSWI_Reason_GetCmdLine semihosting invocation are placed into .data section instead of .text - libgloss/aarch64/crt0.S : Idem for aarch64 AngelSVC_Reason_GetCmdLine semihosting.
* libgloss/arm: fix discovery of "eabihf" toolchainsCarlos Santos2017-04-182-2/+2
| | | | | | | | | | | | | ARM EABI toolchains can optionally use the "hf" suffix to identify hardware floating point support. Use the "*-*-eabi*" pattern to match these toolchains. Original patch by Bryan Hundven for the Crosstool-NG project. Improved by Alexey Neyman.

* Fix elf-nano.specs to work without -save-tempsThomas Preud'homme2017-02-151-3/+3
| | | | | | | | | | | | The changes in af272aca591fe1dc0f1be64ae5bda147ea98a047 only works when using gcc/g++ with -E or -save-temps, otherwise newlib's newlib.h gets used even if -specs=nano.specs is specified. This is because the driver only use cpp_options spec for the external cpp tool, not for the integrated one. This patch uses instead cpp_unique_options which is used in all cases: it is used directly when the integrated preprocessor is used, and indirectly by expansion of cpp_options otherwise.
* Fix cpp invocation for C++ in nano specThomas Preudhomme2017-02-131-3/+3
| | | | | | | | | | | Hi, The changes in c028685518a261f6d0dab0d7ed15f9570ab9b3d0 to use newlib-nano's include directory work for cc1 but not cc1plus. cc1plus comes with its own cpp spec which does not have a name attached to it. This patch uses the renaming trick on cpp_options instead of cpp, as cpp_options is used both by cc1 and cc1plus.

* Initializing TTBR0 to inner/outer WBJiong Wang2016-03-261-1/+10
| | | | | | | | | | | | | | | | | | | | | While running tests on internal systems, we identified an issue in the startup code for newlib on AArch32 systems with Multiprocessor Extensions to the architecture. The issue is we were configuring page table flags to be Inner cacheable/Outer non-cacheable, while for at least architectures with Multiprocessor Extension, we'd configure it to Inner/Outer write-back, no write-allocate, and cacheable. The attached patch fixes this, and no regression on arm-none-eabi bare-metal tests. Adopted suggestion given by Richard offline to avoid using jump. libgloss/ * arm/cpu-init/rdimon-aem.S: Set TTBR0 to inner/outer cacheable WB, and no allocate on WB for arch with multiprocessor extension.
