8 years agolinker: don't pass dlextinfo to dependent loads
Dmitriy Ivanov [Wed, 2 Sep 2015 23:32:02 +0000 (16:32 -0700)]
linker: don't pass dlextinfo to dependent loads

Don't pass the parent load's dlextinfo to dependent loads, since this
causes the linker to try to load the dependencies using the same
addresses/relro/fds/etc as the main library, which is never going to
work. This was how it worked before ae69a95 which broke this.

[MIPS] Link .dex or .oat code lacking .MIPS.abiflags segment

This corrects an issue with mips32 Art on mips64r6 Android, where
Java ran slowly due to unintended use of kernel-trap emulation of
single-precision floating point registers. This also regressed all
Art tests due to an extra logcat line
    WARNING: linker: Using FRE=1 mode to run "..."

When targeting mips32r6, Art generates modeless or FR=1 floating point
code, same as Android's own native mips32r6 modules. So the trapping was
unneeded. Linker was confusing Art-generated modules with those from
old NDK compilers, which do need that trapping mode.

This linker filename check may become unnecessary, if Art learns how to
generate .MIPS.abiflags segments in its generated elf-like codefiles.

Stop sending SIGPIPE to debuggerd.

SIGPIPE is a pretty normal way for command-line apps to die, but because
we catch it and report it via debuggerd, we get a lot of bogus bugs. We
could catch SIGPIPE in our tools, but that's not really legit and slightly
misleading.

"But", you say, "catching SIGPIPE is useful for app bugs!". Except a trawl
through buganizer suggests it's misleading there too. Not least because
it's usually an innocent victim that dies --- the problem is usually on the
other end of the pipe (which you learn nothing about because that process
already died, which is what closed the pipe).

We also don't catch SIGALRM, which is another signal that will terminate
your process if you don't catch it, but that one actually represents a
logic error in the crashing process, so there's a stronger argument for
catching that. (Except it too is not a real source of bugs.)
