| * | first commit of the new libm!•••thanks to the hard work of Szabolcs Nagy (nsz), identifying the best
(from correctness and license standpoint) implementations from freebsd
and openbsd and cleaning them up! musl should now fully support c99
float and long double math functions, and has near-complete complex
math support. tgmath should also work (fully on gcc-compatible
compilers, and mostly on any c99 compiler).
based largely on commit 0376d44a890fea261506f1fc63833e7a686dca19 from
nsz's libm git repo, with some additions (dummy versions of a few
missing long double complex functions, etc.) by me.
various cleanups still need to be made, including re-adding (if
they're correct) some asm functions that were dropped.

| * | add deprecated (removed from posix) [efg]cvt() functions•••these have not been heavily tested, but they should work as described
in the old standards. probably broken for non-finite values...

| * | fix signed overflows at most-negative values in ato(i|l|ll)•••patch by Pascal Cuoq (with minor tweaks to comments)
| Rich Felker | 2011-11-10 | 3 | -6/+9 |
| * | fix incorrect long double parameters on arm (and other future ports)•••this was the cause of crashes in printf when attempting to print
floating point values.

| * | fix incorrect overflow errors on strtoul, etc. | Rich Felker | 2011-09-05 | 4 | -8/+20 |
| * | fix various bugs in new integer parser framework•••1. my interpretation of subject sequence definition was wrong. adjust
parser to conform to the standard.
2. some code for handling tail overflow case was missing (forgot to
finish writing it).
3. typo (= instead of ==) caused ERANGE to wrongly behave like EINVAL

| * | fix wcsto[iu]max with high characters•••stopping without letting the parser see a stop character prevented
getting a result. so treat all high chars as the null character and
pass them into the parser.
also eliminated ugly tmp var using compound literals.

| * | new restartable integer parsing framework.•••this fixes a number of bugs in integer parsing due to lazy haphazard
wrapping, as well as some misinterpretations of the standard. the new
parser is able to work character-at-a-time or on whole strings, making
it easy to support the wide functions without unbounded space for
conversion. it will also be possible to update scanf to use the new
parser.

| * | avoid crashing when nel==0 is passed to qsort | Rich Felker | 2011-04-29 | 1 | -2/+6 |
| * | replace heap sort with smoothsort implementation by Valentin Ochs•••Smoothsort is an adaptive variant of heapsort. This version was
written by Valentin Ochs (apo) specifically for inclusion in musl. I
worked with him to get it working in O(1) memory usage even with giant
array element widths, and to optimize it heavily for size and speed.
It's still roughly 4 times as large as the old heap sort
implementation, but roughly 20 times faster given an almost-sorted
array of 1M elements (20 being the base-2 log of 1M), i.e. it really
does reduce O(n log n) to O(n) in the mostly-sorted case. It's still
somewhat slower than glibc's Introsort for random input, but now
considerably faster than glibc when the input is already sorted, or
mostly sorted.

| * | fix broken unsigned comparison in wcstoumax | Rich Felker | 2011-04-07 | 1 | -1/+1 |
| * | fix various bugs in strtold:•••0e10000000000000000000000000000000 was setting ERANGE
exponent char e/p was considered part of the match even if not
followed by a valid decimal value
"1e +10" was parsed as "1e+10"
hex digits were misinterpreted as 0..5 instead of 10..15
| Rich Felker | 2011-04-03 | 1 | -10/+13 |
| * | fix all implicit conversion between signed/unsigned pointers•••sadly the C language does not specify any such implicit conversion, so
this is not a matter of just fixing warnings (as gcc treats it) but
actual errors. i would like to revisit a number of these changes and
possibly revise the types used to reduce the number of casts required.

| * | don't compare elements with themselves during qsort.•••this is actually a workaround for a bug in gcc, whereby it asserts
inequality of the keys being compared...

| * | more header fixes, minor warning fix | Rich Felker | 2011-02-14 | 3 | -2/+4 |
