I still have to improve env testing on libc-test side, but I think I'm done with code tuning on the musl side, and pretty happy with the result. Patches 2 and 3 are followups to stuff discussed on IRC; I feel they are not essential. Patch 1 is the overhaul itself. I hope that new code is easy to follow. It should also improve code size nicely; on x86-64 I got (.text size change after patch 1/3 only; .bss grows by one pointer): text text filename 17 17 obj/src/env/clearenv.o 140 97 obj/src/env/getenv.o 491 334 obj/src/env/putenv.o 215 284 obj/src/env/setenv.o 283 140 obj/src/env/unsetenv.o Thanks. Alexander
