+# 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.)
