4778a2a62f lesson learned from http://k1024.org/~iusty/blog/entry/perf-null/ – add -DMKSH_SMALL_BUT_FAST which gives more speed (8/20K less cycles, 5/9K less insns, 1.8/2.4k less branches, 65/275 less branch misses) on Debian/amd64 (klibc-static/eglibc) at cost of 0/2 more page faults and 6K/6K more text size 2012-07-01 15:55:00 +00:00

4c65f518af RT says: libc5 uses __inline__ for its inline stuff, but lcc doesn't support __inline__ but __inline 2012-05-18 01:38:04 +00:00

1eebfa8b85 check whether klibc sigsuspend() is usable: RT or hpa’s two new methods; if not, deactivate it 2012-05-17 19:36:41 +00:00
tg
6b2aa91ddd add a way to detect varying C libraries or other stuff “extra type” 
(for now klibc) alongside “compiler type”

if klibc, add -DMKSH_NO_LIMITS automatically

d05c7c4867 recognise (but don’t do anything with, yet) lcc (from RT) 2012-05-17 18:54:28 +00:00
tg
b89b96a4ab RT says not using sigsuspend helps Syllable (but is still buggy, see http://forum.syllable.org/viewtopic.php?p=8171 and probably (doesn’t work for me) http://pyro-os.org/?section=Forum&forum=Bugs&zpbw_postKey=NUgSMp85XGHKbF751zJ6Ww which show the bug affects all shells) 2012-05-09 23:20:42 +00:00

5488e79d3b introduce a nosymlink check category (idea by RT); pass it to test.sh; use cp if ln -s fails (me) 2012-05-04 21:42:51 +00:00

b1aa05e36e do not use $(uname -s || uname) as TARGET_OS if it’s the same as $(uname -n), to weave around many ancient unicēs; idea discussed with RT 2012-05-04 21:37:08 +00:00

tg
2d0ca10629 patch test.sh to support check.t split into multiple chunks 
which is apparently needed on Coherent due to OS limits

inspired by a patched test.sh from RT, except I require a
dot before the sequence number for easier globbing, made
the splitting use -S, and the errorlevel is more correct
 2012-05-04 21:28:06 +00:00
tg
5780bc5eb7 new MKSH_NO_CMDLINE_EDITING to disable command line editing in its entirety 
mainly for the Plan 9 port though it may also help the WinAPI variant,
other porting efforts, as well as a new project I cannot say yet

tg
b67de6ba17 add experimental code to use sigprocmask+pause+sigprocmask ipv sigsuspend (and harden j_sigchld handler for that) to improve working on BeOS 5.0 and Coherent UNIX, found by RT 2012-04-27 16:16:23 +00:00

29e4269f33 if the OS does not provide sig_atomic_t and/or ssize_t, you can now define 
MKSH_TYPEDEF_SIG_ATOMIC_T and MKSH_TYPEDEF_SSIZE_T via CPPFLAGS to the
*correct* definitions (it’s absolutely critical they be correct!)

0af5e1f288 can’t forget LynxOS, although it’s still preliminary… 2012-04-06 23:10:50 +00:00
tg
3d3081115b if LDSTATIC is not empty (i.e. "-static" or " "), always add “our” sources: 
• strlcpy
• utf_wcwidth
note strchr/strstr from misc.c are still #ifdef DEBUG only, as they are
not eligible: they’re for const-cleanliness debugging purposes

XXX get rid of multiple occurrences of binary search code, too…
 2012-04-06 15:20:42 +00:00

6ca4228e7c disabling jobs just when there is no ctty isn’t needed, at least for BeOS 
XXX recheck this with all the others, e.g. NeXTstep

3b2d9322ec change signal probing order: prefer e.g. SEGV over BUS when same Nr. (BeOS) 2012-04-01 17:17:45 +00:00

412a96d29a speed up Generating list of signal names (XXX can we wrap this into one compile, anyway?) 2012-04-01 16:40:26 +00:00
tg
607a2af260 found the actual reason… cc -E does syntax check and wrap with whitespace ☹ 
also we can only do NeXTstep 3.3 with -posix, but not 3rdpty egcs or OS 4.2

a3fd4f62e6 • move behavioural changes topmost (locale, zsh emulate sh, solaris xpg) 
• attempt to handle cpp on nextstep by using -save-temps
• work around another nextstep bug that may or may not hit us, found by RT:
  ‣ http://lists.gnu.org/archive/html/autoconf/2003-11/msg00094.html
• hide "dirname: command not found", scary even if it might help debugging
