beam_debug: Fix printing of f operand for catch_yf
beam_debug: Print out strings for bs_match_string/bs_put_string

Matching out an 8-bit integer is faster than matching out
an utf8-encoded code point, even if the value of the code
point is less than 128. The reason is that matching out
an 8-bit integer is specially optimized to avoid a function
call. Do a similar optimization for matching out an utf8
segment.

The call "erlang:get_stacktrace()" is not handled explicitly. If there
are issues, they can probably be ignored since erlang:get_stacktrace/1
will be deprecated and removed.

Before:

After:
1> binary_to_integer(<<":">>, 16).
** exception error: bad argument
in function binary_to_integer/2
called as binary_to_integer(<<":">>,16)
Prior to this change, both list_to_integer/2 and binary_to_integer/2
would convert strings with values between ASCII '9' up to '0'+base for
base > 10. For example, when converting in base 16, you could pass ':',
';', '<', '=', '>', and '?' without getting an exception. This was due
to a missing check in c2int_is_invalid_char().
This change adds the missing check and a regression test for passing
':'. It also simplifies the code and tightens up an out-of-bounds check
to make it off-by-one rather than off-by-two.

Fix GC bug for HiPE primop bs_put_utf8
|
|
in order to detect incompatible changes in primop interface
(which we just did for bs_put_utf8) and refuse hipe loading.
|
|
by preventing it from doing GC, which generated code relies on.
|
|
This is *ONLY* relevant for drivers/NIFs, so it's probably counter-
productive to document it elsewhere.
|
|
Previously we accepted trailing NULs, which was backwards compatible
as such usage never resulted in misbehavior in the first place. The
downside is that it prevented erts_native_filename_need from
returning an accurate number of *actual characters*, needlessly
complicating encoding-agnostic code like erts_osenv.
|
|
The standard search order does not include the directory that the
loaded DLL resides in, requiring dirty $PATH hacks to get things
working, which is not an option now that os:putenv/2 is divorced
from the OS environment.
|
|
putenv(3) and friends aren't thread-safe regardless of how you slice
it; a global lock around all environment operations (like before)
keeps things safe as far as our own operations go, but we have
absolutely no control over what libc or a library dragged in by a
driver/NIF does -- they're free to call getenv(3) or putenv(3)
without honoring our lock.
This commit solves this by setting up an "emulated" environment which
can't be touched without going through our interfaces. Third-party
libraries can still shoot themselves in the foot but benign uses of
os:putenv/2 will no longer risk crashing the emulator.

Symptom: "Closing pipe in state Waiting. Event lost?"

Do erlang:yield() instead of busy spinning in "Waiting" state.
