* | ps: obtain applet names from other BusyBox processesRon Yorston2018-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the code which passed applet names to child processes using environment variables. This only allowed ps to display names for its ancestors. Instead attempt to read applet names from the memory of unrelated processes. The Microsoft documentation alone wasn't enough to figure out how to do this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this change, BB_EXTRA_VERSION of "" resulted in: "BusyBox v1.28.0.git () multi-call binary" message, after the fix it is: "BusyBox v1.28.0.git multi-call binary" While at it, eliminate BB_BT and BANNER single-use macros.

* | mingw: add -fno-ident to CFLAGSRon Yorston2016-02-221-2/+1
| | | | | | | | | | | | | | | | Without this flag a compiler version string is injected into each binary object. The linker doesn't deduplicate the strings, leading to bloat. This enhancement was suggested by Viktor Szakats. It saves 13KB.

| | | | | | | | | | | | | | | | | | Building & running with ASAN is super helpful, so add a dedicated config knob for it. This way people don't have to guess at the right compiler settings in order to get a good build. We can just tell people to enable this one option. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * build system: stop .eh_frame generationDenys Vlasenko2012-09-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Rich Felker: By default, modern GCC generates DWARF2 debug/unwind tables in the .eh_frame section of the object files/binaries. This adds significant bloat (as much as 15%) to the size of the busybox binary, including the portion mapped/loaded into memory at runtime (possibly a big issue for NOMMU targets), and the section is not strippable with the strip command due to being part of the loaded program text. I've since done some further checking - both testing and asking the GCC developers about it - and it seems the solution is to add to the CFLAGS -fno-unwind-tables and -fno-asynchronous-unwind-tables. If debugging is disabled, this will prevent GCC from outputting DWARF2 tables entirely. But since busybox builds with -g by default, the interesting case is what happens then. I originally thought these options would break debugging, but they don't; instead, they tell GCC to output the DWARF2 tables in the .debug_frame section instead of the newish .eh_frame section (used for exception handling). With these options added, busybox_unstripped is still fully debuggable, and the final busybox binary loses the 15% bloat factor from the DWARF2 tables.

| * disable format security warningsMike Frysinger2012-08-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We pass strings to printf directly a lot. Some distros enable some flags in their gcc by default like -Wformat-security. With these two things, we end up with a lot of build warnings like so: loginutils/chpasswd.c:42:3: warning: format not a string literal and no format arguments [-Wformat-security] But we don't care. Our focus is first and foremost on size, so adding a lot of dummy calls like: - printf(some_constant_string); + printf("%s", some_constant_string); is pointless bloat. Disable this warning flag if the compiler supports it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Compile options: default to -O2 when -Os is not availableWolfgang Denk2011-05-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent versions of GCC for PowerPC systems suffer from some compiler bugs which prevent the use of "--enable-target-optspace" in their configuration, which makes the compiler option "-Os" unavailable; for reference see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48278 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45053 In the result, BusyBox will be compiled without any optimization options, which causes a huge binary (1.8 MiB for default configuration on PPC, built with gcc 54.51 from the Yocto / Poky / OpenEmbedded tool chains). This commit changes behaviour so "-O2" gets used as fallback when "-Os" is not available. This reduces the image size in above test to 1.3 MiB. This is still 10...15% more then what we get with "-Os", but much better than using no optimization at all.
