The code is (almost) a direct copy of the current arm26 sources.
It's identical to the current arm32 sources, with the following exceptions:
- _C_LABEL is used on references to C labels from assembler.
- Function returns in assembler have APCS-26 versions in #ifdef __APCS_26__.
- It uses SoftFloat 2a rather than SoftFloat 1a.
The first two of these should be inconsequential. I believe that SoftFloat 2a
should work on arm32 and be backward-compatible with existing code, but this
is not obviously true. For now, arm32 remains using its own bits of libc.
- icmptype (offset of ICMP type field)
- icmpcode (offset of ICMP code field)
- tcpflags (offset of TCP flags field)
and field values:
- icmp-echoreply, icmp-unreach, icmp-sourcequench,
icmp-redirect, icmp-echo, icmp-routeradvert,
icmp-routersolicit, icmp-timxceed, icmp-paramprob,
icmp-tstamp, icmp-tstampreply, icmp-ireq, icmp-ireqreply,
icmp-maskreq, icmp-maskreply
- tcp-fin, tcp-syn, tcp-rst, tcp-push, tcp-ack, tcp-urg
This allows expressions like the following:
icmp[0] = 3
(tcp[13] & 0x02) != 0
to be written as:
icmp[icmptype] = icmp-unreach
(tcp[tcpflags] & tcp-syn) != 0
which is a bit more user-friendly for e.g. writing packet filter rules.
ld.elf_so with citrus locale, it bombs.
XXX this is shortterm workaround. if you are willing to test citrus locale,
use RUNE=yes in libc/locale/Makefile.inc.
implement displaying of possible completions, add hook to display the list
on second rl_complete() invocation in row (typically, double <TAB>)
This addresses the completion part of lib/11581 by Richard Earnshaw.
(1) alloate two mbstate_t, for input/output, per a file stream.
(2) correct inbound escape sequence processing.
cope with incomplete string better. keep intermediate state for single shifts.
let C0/C1 go through.
XXX for (1), we should expand FILE structure, but is possible only with
libc major # bump.
for LC_ALL, return success if at least on of categories was loaded
successfully, error if no category was loaded; in the latter case, we don't
need to back off locale changes, since none happened
