Richard Earnshaw f973a7d8be arm: Finish moving newlib to unified syntax for Thumb1 
Most code in newlib already uses unified syntax, but just a couple of
laggards remain.  This patch removes these and means the the entire
code base has now been converted.

Thomas Preud'homme 69f4c40291 Make macro checks ARMv8-M baseline proof 
libgloss:

        * arm/Makefile.in: Add newlib/libc/machine/arm to the include path if
        newlib is present.
        * arm/arm.h: Include acle-compat.h.
        (THUMB_V7_V6M): Rename to ...
        (PREFER_THUMB): This.  Use ACLE macros __ARM_ARCH_ISA_ARM instead of
        __ARM_ARCH_6M__ to decide whether to define it.
        (THUMB1_ONLY): Define for Thumb-1 only targets.
        (THUMB_V7M_V6M): Rename to ...
        (THUMB_VXM): This.  Defined based on __ARM_ARCH_ISA_ARM, excluding
        ARMv7.
        * arm/crt0.S: Use THUMB1_ONLY rather than __ARM_ARCH_6M__,
        !__ARM_ARCH_ISA_ARM rather than THUMB_V7M_V6M for fp enabling, and
        PREFER_THUMB rather than THUMB_V7_V6M.  Rename other occurences of
        THUMB_V7M_V6M to THUMB_VXM.
        * arm/linux-crt0.c: Likewise.
        * arm/redboot-crt0.S: Likewise.
        * arm/swi.h: Likewise.
        * arm/trap.S: Likewise.

newlib:

        * libc/machine/arm/memcpy-stub.c: Use ACLE macros __ARM_ARCH_ISA_THUMB
        and __ARM_ARCH_ISA_ARM to check for Thumb-2 only targets rather than
        __ARM_ARCH and __ARM_ARCH_PROFILE.
        * libc/machine/arm/memcpy.S: Likewise.
        * libc/machine/arm/setjmp.S: Likewise for Thumb-1 only target and
        include acle-compat.h.
        * libc/machine/arm/strcmp.S: Likewise for Thumb-1 and Thumb-2 only
        target and include acle-compat.h.
        * libc/sys/arm/arm.h: Include acle-compat.h.
        (THUMB_V7_V6M): Rename to ...
        (PREFER_THUMB): This.  Use ACLE macro __ARM_ARCH_ISA_ARM instead of
        __ARM_ARCH_6M__ to decide whether to define it.
        (THUMB1_ONLY): Define for Thumb-1 only targets.
        (THUMB_V7M_V6M): Rename to ...
        (THUMB_VXM): This.  Defined based on __ARM_ARCH_ISA_ARM, excluding
        ARMv7.
        * libc/sys/arm/crt0.S: Use PREFER_THUMB rather than THUMB_V7_V6M and
        rename THUMB_V7M_V6M into THUMB_VXM.
        * libc/sys/arm/swi.h: Likewise.

Jeff Johnston 5900080d7d 2009-05-13 Paul Brook <paul@codesourcery.com> 
* libc/machine/arm/setjmp.S: Don't bother saving IP.  Copy SP to
        IP before saving.  Likewise when restoring.

Jeff Johnston eba36c51fa 2009-05-13 Paul Brook <paul@codesourcery.com> 
* libc/machine/arm/setjmp.S: Add ARMv6-M implementation.
 2009-05-13 18:28:49 +00:00
Nick Clifton 026f9d290f * libc/machine/arm/setjmp.S: Fix thumb2 support. 
* arm/crt0.S: Allow assembly under ARMv7 ISA.  Support for
            initializing stack pointers for interrupt modes is still pending.

Jeff Johnston 9bbe6d5d28 2006-02-07 Paul Brook <paul@codesourcery.com> 
* libc/machine/arm/setjmp.S: Add Thumb-2 support.
        * libc/sys/arm/crt0.S: Add Thumb-2 startup code.
        * libc/sys/arm/libcfunc.c (do_AngelSWI): Use AngelSWIInsn.
        * libc/sys/arm/swi.h (AngelSWIInsn, AngelSWIAsm): Define.
        * libc/sys/arm/trap.S: Disable for Thumb-2.

Jeff Johnston a170abec08 2004-06-09 Toralf Lund <toralf@procaptura.com> 
* libc/sys/arm/setjmp.S, libc/sys/arm/access.c: Move
        files from libc/sys/arm to libc/machine/arm.
        * libc/machine/arm/Makefile.am, libc/machine/arm/Makefile.in: Add
        library build support for files moved from libc/sys/arm.
        * libc/sys/arm/Makefile.am, libc/sys/arm/Makefile.in:  Remove
        references to access and setjmp.
        * configure.host: Add checks for newlib_may_supply_syscalls to
        determine whether or not to use sys/arm directory and use
        special compiler flags: ARM_RDI_MONITOR and ARM_RDP_MONITOR.
