The size of a structure (as measured by the @code{sizeof} -+operator) never changes between @option{-mno-reverse-bitfields} and -+@option{-mreverse-bitfields}. Nonetheless, there can be some -+confusing corner cases with structs where the compiler has to add -+additional padding to meet alignment restrictions. Consider: -+ -+@smallexample -+struct inner -+@{ -+ unsigned int a:1; -+ unsigned int b:15; -+@}; -+ -+union outer -+@{ -+ struct inner inner; -+ unsigned int val; -+@}; -+ -+unsigned int f() -+@{ -+ union outer o; -+ o.val = 0; -+ o.inner.b = 1; -+ return o.val; -+@} -+@end smallexample -+ -+a call to @code{f} will return 2 when compiled with -+@option{-mno-reverse-bitfields} (the default), or 65536 when compiled -+with @option{-mreverse-bitfields}. This is because @code{sizeof -+(inner)} is 4 in both cases. In the @option{-mno-reverse-bitfields} -+case, the compiler pads the struct at the end to be 4 bytes long, -+effectively doing: -+ -+@smallexample -+struct inner -+@{ -+ unsigned int a:1; -+ unsigned int b:15; -+ unsigned int padding:16; -+@}; -+@end smallexample -+ -+In the @option{-mreverse-bitfields} case, the hidden padding is -+reversed along with everything else, yielding the equivalent of: -+ -+@smallexample -+struct inner -+@{ -+ unsigned int padding:16; -+ unsigned int b:15; -+ unsigned int a:1; -+@}; -+@end smallexample -+ -+Of course, if we would rather that @code{sizeof (inner)} was 2, we could -+write the struct as: -+ -+@smallexample -+struct inner -+@{ -+ unsigned short a:1; -+ unsigned short b:15; -+@}; -+@end smallexample -+ -+and the padding would go away. -+ -+In some cases, especially when using the @code{__packed__} attribute, -+there is no well-defined bit reversal that is possible: the compiler -+will issue an error message in this case. Consider: -+ -+@smallexample -+struct invalid -+@{ -+ unsigned int f1:1; -+ unsigned int f2:15; -+ unsigned int f3:4; -+ unsigned int f4:4; -+@} __attribute__ ((__packed__)); -+@end smallexample -+ -+Since @code{sizeof (invalid)} is 3, we are forced to try reversing -+individual bytes in the struct. But f2 is more than a byte wide, so -+we can't reverse it and still have it be contiguous. Similar cases -+occur when dealing with arrays or other large contiguous objects: -+ -+@smallexample -+struct invalid2 -+@{ -+ unsigned char f1[5]; -+ unsigned char f2[3]; -+@}; -+@end smallexample -+ -+You'll have to rewrite the affected structs to say exactly what you -+mean in odd cases like that. -+ -+Finally, note that individual fields are sized as a whole. The structs -+ -+@smallexample -+struct array1 -+@{ -+ unsigned char f1[3]; -+ unsigned char f2; -+@} -+@end smallexample -+ -+and: -+ -+@smallexample -+struct array2 -+@{ -+ unsigned char f1a; -+ unsigned char f1b; -+ unsigned char f1c; -+ unsigned char f2; -+@} -+@end smallexample -+ -+are not equivalent. When compiled with @option{-mreverse-bitfields}, -+they behave the same as: -+ -+@smallexample -+struct array1r -+@{ -+ unsigned char f2; -+ unsigned char f1[3]; -+@} -+@end smallexample -+ -+and: -+ -+@smallexample -+struct array2r -+@{ -+ unsigned char f2; -+ unsigned char f1c; -+ unsigned char f1b; -+ unsigned char f1a; -+@} -+@end smallexample -+ -+would, respectively, when compiled with -+@option{-mno-reverse-bitfields}. In particular, f1 is treated as a -+single contiguous 24-bit object for purposes of reversal, while f1a, -+f1b, and f1c are treated as individual 8-bit objects that need not -+(and do not) remain contiguous.

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.
