Cross-profiling support: relocate .gcda files when
running at system other than executable been built on.
* gcov-io.c (gcov_open): When in libgcov library
use given data file relocation prefix to build file name.
* gcov-io.h (gcov_open): Updated proto to accept
data file relocation prefix.
* libgcov.c (create_file_directory): New function.
(gcov_prefix): New static variable to hold data file
relocation prefix.
(gcov_version): Use relocation prefix.
(gcov_exit): Always try to create directory for output
file. Relocate filename at each use.
(__gcov_init): Initialize directory relocation prefix
if required. Strip off leading directories from
the initial filename.
* tsystem.h: include filenames.h
(DIR_SEPARATOR): Macro copied from system.h.
(DIR_SEPARATOR_2): Likewise.
* doc/gcov.texi (Cross-profiling): New node documenting
cross-profiling management.
* doc/invoke.texi (-fprofile-arcs): xref to cross-profiling.

+@section Data files relocation to support cross-profiling
+
+Running the program will cause profile output to be generated. For each
+source file compiled with @option{-fprofile-arcs}, an accompanying @file{.gcda}
+file will be placed in the object file directory. That implicitly requires
+running the program at the same system as it was build or having same
+absolute directory structure on the target system (program will try
+to create needed directory structure).
+
+To support cross-profiling, program compiled with @option{-fprofile-arcs}
+performs data file relocation basing on two environment variables:
+
+@itemize @bullet
+@item
+GCOV_PREFIX contains the prefix to add to the absolute paths
+in the object file.
+
+@item
+GCOV_PREFIX_STRIP indicates the how many initial directory names to strip off
+the hardwired absolute paths. Default value is 0.
+@end itemize
+
+For example, if object file @file{/user/build/foo.o} was build with
+@option{-fprofile-arcs}, the final executable will try to create data file
+@file{/user/build/foo.gcda} when running at the target system and will
+fail if corresponding directory does not exists and is not allowed to create.
+
+In this case, manipulating environment variables you can relocate data file
+to the suitable local directory. For our example, setting @samp{GCOV_PREFIX=/target/run}
+and @samp{GCOV_PREFIX_STRIP=1} values will force use of @file{/target/run/build/foo.gcda}
+file name.

#
# Description:
#
# Nicholas Pitre released this patch for gcc soft-float support here:
# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
#
# This version has been adapted to work with gcc 3.4.0.
#
# The original patch doesn't distinguish between softfpa and softvfp modes
# in the way Nicholas Pitre probably meant. His description is:
#
# "Default is to use APCS-32 mode with soft-vfp. The old Linux default for
# floats can be achieved with -mhard-float or with the configure
# --with-float=hard option. If -msoft-float or --with-float=soft is used then
# software float support will be used just like the default but with the legacy
# big endian word ordering for double float representation instead."
#
# Which means the following:
#
# * If you compile without -mhard-float or -msoft-float, you should get
# software floating point, using the VFP format. The produced object file
# should have these flags in its header:
#
# private flags = 600: [APCS-32] [VFP float format] [software FP]
#
# * If you compile with -mhard-float, you should get hardware floating point,
# which always uses the FPA format. Object file header flags should be:
#
# private flags = 0: [APCS-32] [FPA float format]
#
# * If you compile with -msoft-float, you should get software floating point,
# using the FPA format. This is done for compatibility reasons with many
# existing distributions. Object file header flags should be:
#
# private flags = 200: [APCS-32] [FPA float format] [software FP]
#
# The original patch from Nicholas Pitre contained the following constructs:
#
# #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
# %{mhard-float:-mfpu=fpa} \
# %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
#
# However, gcc doesn't accept this ";:" notation, used in the 3rd line. This
# is probably the reason Robert Schwebel modified it to:
#
# #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
# %{mhard-float:-mfpu=fpa} \
# %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
#
# But this causes the following behaviour:
#
# * If you compile without -mhard-float or -msoft-float, the compiler generates
# software floating point instructions, but *nothing* is passed to the
# assembler, which results in an object file which has flags:
#
# private flags = 0: [APCS-32] [FPA float format]
#
# This is not correct!
#
# * If you compile with -mhard-float, the compiler generates hardware floating
# point instructions, and passes "-mfpu=fpa" to the assembler, which results
# in an object file which has the same flags as in the previous item, but now
# those *are* correct.
#
# * If you compile with -msoft-float, the compiler generates software floating
# point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
# order) to the assembler, which results in an object file with flags:
#
# private flags = 600: [APCS-32] [VFP float format] [software FP]
#
# This is not correct, because the last "-mfpu=" option on the assembler
# command line determines the actual FPU convention used (which should be FPA
# in this case).
#
# Therefore, I modified this patch to get the desired behaviour. Every
# instance of the notation:
#
# %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
#
# was changed to:
#
# %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
#
# I also did the following:
#
# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
# be consistent with Nicholas' original patch.
# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
# macros I could find. I think that if you compile without any options, you
# would like to get the defaults. :)
# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
# anymore. (The required functions are now in libgcc.)

# This patch contains various fixes for the thumb code handling in GCC 3.4.4
#
# Most of these are minor fixes to code which is either missing (Linux thumb
# div0, thumb clear instruction cache) or uses the wrong return mechanism
# (libffi)
#
# There is also a significant design problem with the _call_via_rx code -
# it cannot be in a shared library because a call via PLT simply won't
# work (for _call_via_ip) and is very inefficient anyway.
#
# This is fixed in uclibc simply by incorporating the code into crti.S
# (an extra 30 bytes for the 15 functions) even though not all link units
# require all the code - there is so little of it. That doesn't work with
# the crti.asm here because it is linked with libgcc.a which already defines
# these symbols
