There used to be a requirement that Dialyzer was build at the
very end. Since this requirement has been dropped, remove the
special-case build targets for Dialyzer in the top-level
Makefile.

To avoid issues with parallel make and to slightly speed up the
build process, avoid a recursive make by replacing pcre/Makefile.in
with pcre/pcre.mk and including it from the main emulator Makefile.

One input file that generate multiple output file are tricky to
handle in make. One way is to use a stand-in to represent all the
other generated files.

Make sure that directories are created before they are used.
I tried to use order-only prerequisites to create the directories,
but run into two problems: First, order-only prerequisites are
only implemented in Make 3.80 and later. Second, on a computer
running Solaris/Intel 2.8 (with Make 3.80), order-only prerequisites
seemed to work like ordinary prerequisites, causing targets to
be re-built if the timestamp for the directory changed.
Therefore, using a shell command to run mkdir seems to be the
more portable solution.

Create directories first, not within implicit rules. If two
'install' instances runs at the same time attempting to create
a directory, one of them may fail with an "File exists" error.

Add dependecies to force the ct_line parse transform module to be
built before all other modules.

Apparantly, an invocation like "make generate depend" will run the
'generate' and 'depend' targets in parallel, even if the Makefile
contains a .NOTPARALLEL target. In this case, it will result in
incorrect dependencies since not all files have been generated when
the dependencies are computed.
Split up the single 'make' invocation to two invocations, to force the
targets to be run sequentially.

There once was a reason to have a "Makefile.otp" makefile, but
it doesn't apply any longer. Rename it to "Makefile" so that
the standard otp_subdir.mk file can be used for recursion into
sub directories.

Constructing binaries using the bit syntax with literals sizes
that would not fit in an Uint will either cause an emulator crash
or the loading to be aborted.
Use the new TAG_o tag introduced in the previous commit to make sure
that the attempt to create huge binary literals will generate a
system_limit exception at run-time.
|
|
The handling of large values for other tags than TAG_i (integer) is
buggy. Any tag value equal to or greater than 2^40 (5 bytes) will
abort loading. Tag values fitting in 5 bytes will be truncated to 4
bytes values.
Those bugs cause real problems because the bs_init2/6 and
bs_init_bits/6 instructions unfortunately use TAG_u to encode literal
sizes (using TAG_i would have been a better choice, but it is too late
to change that now). Any binary size that cannot fit in an Uint
should cause a system_limit exception at run-time, but instead the
buggy handling will either cause an emulator crash (for values in the
range 2^32 to 2^40-1) or abort loading.
In this commit, implement overflow checking of tag values as a
preparation for fixing the binary construction instructions. If any
tag value cannot fit in an Uint (except for TAG_i), change the
tag to the special TAG_o overflow tag.
|

We want to make sure that a tag/type name is not defined more than
once and that we don't define too many primitive tags. Primitive
tags must be named with lowercase letters (or they will be confused
with variable names in transformations in the ops.tab file).
|
|
Attempting to construct <<0:((1 bsl 32)-1)>>, the largest bitstring
allowed in a 32 bit emulator, would cause an emulator crash because
of integer overflow.
Fix the problem by using an Uint64 to avoid integer overflow.
Do not attempt to handle construction of <<0:((1 bsl 64)-1>> in
a 64-bit emulator, because that will certainly cause the emulator
to terminate anyway because of insufficient memory.
