2017-07-28ash: support platforms that don't have '%m' printf specifierRon Yorston
The '%m' conversion specifier prints an error message based on the current value of 'errno'. It is available in the GNU C library, Cygwin (since 2012), uClibc and musl. It is not available in various BSDs, BSD-derived systems (MacOS, Android) or Microsoft Windows. Use a symbol defined in platform.h to control how error messages can be formatted to display the 'errno' message. On platforms that support it use '%m'; on other platforms use '%s' and strerror(). On platforms that have '%m' there is essentially no change in the size of the binary.

2017-07-28ash: less hackish implementation of evaltreenr()Denys Vlasenko
Defining a function alias with __attribute__ ((alias("evaltree"),__noreturn__)) is not that usual, and clang had a bug which made it misunderstand this construct. Switch to: ALWAYS_INLINE NORETURN evaltreenr() { evaltree(); unreachable(); } Older gcc's do not know unreachable(), on them we pay the price of having a few extra calls to abort(): function old new delta evalsubshell 151 156 +5 evalpipe 357 362 +5 argstr 1141 1144 +3 On newer gcc, code size does not change.

2017-01-09Allow FAST_FUNC to be overridden at build timeKang-Che Sung
Busybox uses FAST_FUNC macro to tweak with IA-32 calling conventions in order to make the function call slightly smaller or slightly faster. However, when I experiment with GCC's LTO (Link Time Optimization), I discovered that FAST_FUNC could hinder LTO's optimization so that the resulting executable become a few bytes larger (than what is compiled without FAST_FUNC). This change allows to specify e.g. CONFIG_EXTRA_CFLAGS="-DFAST_FUNC= -flto" and compile with LTO without a source code hack.
