Tamar Christina 111b6813fb Fix multido compilation on ARM
The previous multi-build implementation was copying the config.status from the parent
multilib directory when building the different semihosting variants. It did so because
the configuration doesn't change. However when you use a relative path to configure it
turns out that the paths inside the config.status are also relative.

To fix this, the srcdir is adjusted from the initial configuration instead of copying it.

Tested on aarch64-none-elf and arm-none-eabi.

Yao Qi 32ca315312 Don't fetch command line options without semi-hosting
Nowadays, the code fetching command line options via semi-hosting are

Tamar Christina 61ddc7a436 Fix crt0 overwriting.
On AArch64 we currently always link in crt0 regardless of if another

an issue before as nosys was not supported on AArch64.

This updates the specs to supply a different crt0 when a semihosting
call is required.

Tamar Christina cd26662dc5 Previous patch to support nosys.specs accidentally broke validation specs because ARM_RDI_MONITOR was never passed to the build rule for crt0.
This fixed the compile for nosys and validation specs
but nosys won't run because of existing limitations to
aarch64's syscalls.c, it requires semihosting to get
commandline arguments and heap info without having a
fallback method as ARM does.

Laurent ALFONSI 9b1167219a ARM/AArch64: Fix GetCmdLine semihosting directives
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.

Thomas Preud'homme be5926babb Fix elf-nano.specs to work without -save-temps
The changes in af272aca59 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.

Hans-Peter Nilsson cd5e7e2d82 Committed, libgloss: hook up cris-elf to the initfini-array support.
After a binutils change "a while ago" (2015-12) to default to
--enable-initfini-array, i.e. to merge .ctors and .dtors into
.init_array and .fini_array, this is needed for cdtors to run at all.

Based on what goes on in arm/ and aarch64/.  Tested for cris-elf by
running the gcc testsuite.

By the way, the configure test doesn't detect this change, so the
HAVE_INITFINI_ARRAY ifdeffery is somewhat redundant.  Still, the
change is tested to be safe with older binutils too.

libgloss/
	* cris/crt0.S, cris/lcrt0.c: Include newlib.h.
	[HAVE_INITFINI_ARRAY] (_init): Define to __libc_init_array.

Anton Kolesov dd00a8e719 arc: Rework default exception handlers for ARC EM and HS
Initially crt0.S used a special function, declared as weak as a default
exception handler in interrupt vector table. To let user override individual
handlers, this function had multiple names - one for each IVT entry, which,
however, was terribly confusing for the debugger and user - because it
wasn't clear which symbol will be used as a function name in debugger.
Defining multiple separate functions - one for each handler, would resolve
the mess, but would increase code size of crt0.o.

To clean this up, this patch defines exception handlers as weak symbols as
well, but those are defined as just symbols, not functions, hence there
would be less confusion over what is what. At the same time, users still can
redefine exception handlers symbol by creating functions with respective
names.

crt0.S for ARC used to use instruction "asr.f lp_count, r3, 2" for all cores

Luckily this is a shift just by 2 bits on all occassions, so fix is trivial
- use two single-bit shifts.

Jeff Johnston cd494f7038 Update crt0.S for ARC.
This is similar to commit 06537f05d4 to the
newlib for ARC.

GCC for ARC has been updated to provide consistent naming of preprocessor
definitions for different optional architecture features:

    * __ARC_BARREL_SHIFTER__ instead of __Xbarrel_shifter for
      -mbarrel-shifter
    * __ARCEM__ instead of __EM__ for ARC EM cores
    * __ARCHS__ instead of __HS__ for ARC HS cores
    * etc (not used in libgloss)

This patch updates crt0.S for ARC to use new definitions instead of a
deprecated ones. To ensure compatibility with older compiler new definitions
are also defined in crt0.S if needed, based on presence of deprecated
preprocessor definitions.

Jiong Wang 18b47e05d3 Initializing TTBR0 to inner/outer WB
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.

DJ Delorie 7d5b16ab9a Build msp430-specific libnosys
The MSP430 debuggers support I/O on hardware through CIO, so
we can use a CIO-enabled library as the "nosys" library (in
addition to the libsim library, which talks to our simulator)

* configure.in: Don't build default libnosys for msp430
* configure: Regenerate.
* msp430/Makefile: Rename libcio to libnosys.

Kevin Buettner 725532a3b2 rl78: Don't output CR when LF is encountered in write().
The file libgloss/rl78/write.c currently contains code which outputs
\r when \n is seen.  The code will then output the \n as well.

This patch removes the bit of code that tests for \n and then outputs
\r.

I made this change to fix some failures in gdb.base/call-ar-st.exp.  In
that test, I see two carriage returns followed by a newline.  One CR is
output by the libgloss code.  The other is output by the terminal driver.

The total list of failures fixed (using the default rl78 multilib) are:

FAIL: gdb.base/call-ar-st.exp: print print_double_array(double_array) (timeout)
FAIL: gdb.base/call-ar-st.exp: print print_char_array(char_array) (timeout)
FAIL: gdb.base/call-ar-st.exp: continue to tbreak2 (timeout)

FAIL: gdb.base/dprintf.exp: call: printf: 2nd dprintf (timeout)

Jeff Johnston 31cf34f849 or1k: Allow exception nesting
Allow exceptions to be nested, which is especially useful with urgent
    interrupts while processing an exception.

    The implementation counts up the nesting level with each call to an
    exception. In the outer exception (level 1), the exception stack is
    started. All nested exceptions just reserve the redzone (scratch
    memory that may be used by compiler) and exception context on the
    stack, but then process on the same scratch.

    Restriction: Impure pointers are shared among all exceptions. This may
    be solved by creating an impure data structure in the stack frame with
    each nested exception.

       * or1k/crt0.S: Add exception nesting
       * or1k/exceptions-asm.S: ditto

Jeff Johnston 5eb4a1666d or1k: set heap start for optimsoc-gzll
- With the gzll kernel we have two different loading options:

  - If the image is loaded to the global memory, the bootstrapping
    loads the kernel to local memory. Applications are loaded on
    demand. The heap then starts right after bss.

  - If the image is pre-loaded to the local memory it includes the
    application binaries right after bss. The heap then starts after
    the application objects.

- We can check if this is a gzll kernel as it has the string "gzll" at
  0x2000. At 0x200c we then find the end of the application objects in
  the image. If there is no global memory we set _or1k_heap_start to
  this value.

    * or1k/boards/optimsoc.S: Heap for gzll kernel
2015-05-27 13:30:20 +02:00
Jeff Johnston 58efeedd16 or1k: Make heap start configurable
- Previously the heap started right after the bss section. This can now
  be configured by changing the _or1k_heap_start symbol that defaults to
  the old value (&end). In board_init_early, we can now set this to
  another value.

    * or1k/sbrk.c: Allow for different heap start

    * or1k/crt0.S: Fix exception stack frame

Jeff Johnston 132030fcf2 Fix interrupt handling for or1k.

- Save the pointer in r16/r18, PICSR in r20 and the current interrupt
  line in r22. Those are callee-saved registers, so that the register
  values will be preserved.

        * or1k/interruts-asm.S: Change registers to callee-saved.
