forked from Imagelibrary/rtems
effc2c4e6b
The patch contains:
* build variants support
* Reworked make-exe custom/*.cfg for all targets (Should be
self-explanatory, may still be incomplete)
* Several fixes to custom/*.cfgs related to setting debug flags
* Fixes to some bsp_specs for BSPs which apparently have never been
build with debugging before ;)
* pc386.cfg fix attempts (cf. my mail from earlier today)
* Updated ampolish (No need to run it, the patch contains the result
from having applied it)
Known bugs/deficiencies related to this work:
* "make [clean|distclean]" support is still incomplete (e.g. "make
clean" does not delete all Depends-o-*)
* Completely untested for linux/posix and hppa.
* Build failures of i960 BSPs (make VARIANT=DEBUG) - I guess, they are
not related to this patch.
* Successfully tested for all sh, sparc, i386, ppc, m68k BSPs (make
VARIANT=DEBUG)
* make VARIANT=PROFILE not supported by all BSPs (I don't care :)
* make VARIANT=DEBUG failures below tests/ for some BSPs (e.g. gensh1),
because of the tests's binaries being too large to fit into the target
memory layout.

# NDEBUG (C library)
|

# if defined asserts do not generate code. This is commonly used

|
# as a command line option.

#
|

# RTEMS_TEST_NO_PAUSE (RTEMS tests)
|
|
# do not pause between screens of output in the rtems tests
|

# If defined, debug checks in RTEMS and support library code are enabled.

# CONSOLE_USE_POLLED (psim_bsp)
|
|
# CONSOLE_USE_INTERRUPTS (psim_bsp)
|
|
# The psim console driver has the structure to operate in either
|
|
# polled or interrupt mode. However both modes only trap to the

# monitor currently.

# PPC_VECTOR_FILE_BASE (ppc)
|
|
# This defines the base address of the exception table.

# NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
|
|
#
|
|
# PPC_ABI (ppc)
|
|
# This defines the calling convention (Application Binary Interface)
|
|
# used in this configuration. EABI is the only one supported.
|
|
#
|
|
# PPC_ASM (ppc)
|
|
# This defines the assembly language format used in this configuration.
|
|
# ELF is the only one supported.
|
|
#
|
|
# PPC_USE_SPRG (RTEMS PowerPC port)
|
|
# If defined, then the PowerPC specific code in RTEMS will use some
|
|
# of the special purpose registers to slightly optimize interrupt
|
|
# response time. The use of these registers can conflict with
|
|
# other tools like debuggers.
|
|
#
|
|
# PPC_USE_DATA_CACHE (RTEMS PowerPC port/BSP)
|
|
# If defined, then the PowerPC specific code in RTEMS will use
|
|
# data cache instructions to optimize the context switch code.
|
|
# This code can conflict with debuggers or emulators. It is known
|
|
# to break the Corelis PowerPC emulator with at least some combinations
|
|
# of PowerPC 603e revisions and emulator versions.
|
|
# The BSP actually contains the call that enables this.
|
|
#
|
|
# PPC_USE_INSTRUCTION_CACHE (RTEMS PowerPC port/BSP)
|
|
# If defined, then the PowerPC specific code in RTEMS will use
|
|
# data cache instructions to optimize the context switch code.
|
|
# This code can conflict with debuggers or emulators.
