dlsym(RTLD_NEXT, func_name). This fails for pthread_join() as it
is present both as a stub in libc and as real operation in libpthread
and the search order is "libtsan.so libc.so libpthread.so".
Force the order "libtsan.so libpthread.so libc.so" so symbols
get intercepted from libpthread first.
Ok: Matthew Green <mrg@netbsd.org>
These two cases are processed in an almost entirely different way. In
particular, copy_comment_nowrap should copy the comment verbatim, which
is not obvious from the current code, due to the many conditions and the
complex control flow.
No functional change.
This gets rid of two members of parser_state. No functional change for
well-formed programs. The sequence of '++int' or '--size_t' may be
formatted differently than before, but no program is expected to contain
that sequence.
Rename lsym_ident to lsym_word since 'ident' was too specific. This
token type is used for constants and string literals as well. Strictly
speaking, a string literal is not a word, but at least it's better than
before.
binaries on a 64-bit platform[*], as such:
- Make the logic about which "sendsig" flavor to call MI (as it is in the
native 64-bit environment) and follow the same rules as the native 32-bit
environment.
- Make COMPAT_NETBSD32 x COMPAT_16 work the same as it would in the
native 32-bit environment by providing a netbsd32_sendsig_sigcontext_16_hook,
rather than overriding the entire sendsig logic with a netbsd32_sendsig_hook.
- In netbsd32___sigaction_sigtramp(), make sure the compat_netbsd32_16
module is loaded if the trampoline version specifies a sigcontext style
handler, otherwise return EINVAL so that libc can try again with siginfo
style.
[*] ...except for arm32, which uses it to mean "run 32-bit OABI binaries
from the 32-bit EABI environment". Doing it this way was arguably a mistake,
but we are stuck with it for now, so support it by providing a machine-
dependent override for netbsd32_sendsig() that also disables the corresponding
logic in netbsd32___sigaction_sigtramp().
Fixes PR kern/56487.
sensor such as:
https://www.adafruit.com/product/2857
This is a higher priced sensor with a lot of features, including the
ability to do sub-second periodic updates. The driver supports
everything about the sensor except for the alert pin.
- Tweak title.
- Clarify semantics -- round down, not any other way.
- xref ffs(3)
- Fix return type: int.
- Fix language about input type.
. Any unsigned type is fine.
. Types smaller than uint32_t will be safely converted to uint32_t.
- Note that it is a constant expression if x is constant.
Before the symbols from the tokenizer had the prefix 'lsym', the symbols
could not be simply called 'else' and 'do'. The functions for processing
the tokens followed that naming scheme.
When the prefix 'lsym' was introduced, the word 'keyword' was no longer
needed, neither in the constants nor in the function names.
No functional change.
__HAVE_STRUCT_SIGCONTEXT in order to support the old
"sigcontext" style of handlers for 32-bit binaries.
However, we only support 32-bit EABI binaries on AArch64,
and by happy accident (due to a libc bug introduced in
2006), 32-bit NetBSD EABI binaries never used "sigcontext"
style handlers. So, we don't need to carry any of this
baggage forward.
This addresses the AArch64 case of PR kern/56487.
- if_wm.c rev. 1.695 for PR kern/40981 still had a problem. The workaround
flag was unexpectedly cleared when a cable is not connected, SIOCINITIFADDR
was called, or if_init was called. Fix it.
- Add debug printf()s.
Since io.c 1.20 from 2019-10-19, indent has not placed error comments in
the code anymore. Since these comments are supposed to be cleaned up
immediately, there is no point in having code for handling them.
