all: remove $OBJTYPE from build

2020-12-30T12:53:28+00:00

Now that we assume pthreads, the only assembly
left is in libmp and libsec.
We only ever added assembly for 386.
The portable C code is fine for plan9port.

Trivial changes: whitespace and modes.

2020-01-10T14:54:30+00:00

Remote whitespace at the ends of lines.
Remove blank lines from the ends of files.
Change modes on source files so that they
are not executable.

all: remove .cvsignore files

2017-09-14T15:25:17+00:00

Rename following .cvsignore files to .gitkeep since they are
required by the build (directories must exist before build):
	- bin/fossil/.gitkeep
	- bin/fs/.gitkeep
	- bin/venti/.gitkeep

libsec: avoid undefined C

2013-03-19T18:35:16+00:00

gcc compiles `p + length < p' into 'length < 0' since pointer overflow is undefined behavior in C.  This breaks the check against a large `length'.

Use `length > pend - p' instead.

There's no need to check `length < 0' since `length' is from length_decode() and should be non-negative.

===

Try the simplified code.

void bar(void);
void foo(unsigned char *p, int length)
{
        if (p + length < p)
                bar();
}

$ gcc -S -o - t.c -O2
...
foo:
.LFB0:
        .cfi_startproc
        testl	%esi, %esi
        js	.L4
        rep
        ret
.L4:
        jmp	bar
        .cfi_endproc

Clearly `p' is not used at all.

arm: build fixes

2011-05-18T17:20:56+00:00

Get p9p to build cleanly for ARM - based on suggestions from rsc and eekee, plus a final tweak from me.  Tested (a bit) on sheevaplug (ubuntu jaunty), Nokia N800 (maemo 4) and Nokia N900 (maemo 5).
