2011-08-16Rewrite stack handlingBjörn Gustavsson
Problems with the current stack implementation: * The GUI assumes that the stack frame pushed on the stack is level 2. If the 'no_tail' option is set for the process, there may not be an entry for level 2. * In each stack entry, the line number is the line number of the caller, not the line number for the function in the 'mfa' field as might be expected. That complicates generation of a stacktrace with line number information. Change the implementation as follows: * Keep the information for the current function (its MFA and current line number) in the #ieval{} record. Don't push it onto the stack. Only push the information when another function is called. That will ensure that the MFA and the line number is found in the same stack entry. That also has the advantage that if the 'no_tail' option is set, the stack not need to be modified for tail-recursive calls. * Make sure that there always is an entry for level two.
2011-08-16Slightly clean-up and optimize some evaluation codeBjörn Gustavsson
There is no need to set #ieval.top to false in every iteration of eval_list/1.
2011-08-16ieval record: Rename the misnamed 'last_call' field to 'top'Björn Gustavsson
The 'last_call' is badly named. What is means is that the next call will leave intepreted code.

2011-08-16dbg_iload: Remove unnecessary handling of old guard testsBjörn Gustavsson
sys_pre_expand has already rewritten old guard tests to new guard tests.
2011-08-16Remove the special handling of Mod:module_info/{0,1}Björn Gustavsson
Many releases ago, Mod:module_info/{0,1} used to be specially handled in the BEAM loader. The debugger has similar special handling. In the current implementation, Mod:module_info/{0,1} are ordinary functions that call special BIFs to do their work. Therefore, remove the special handling of Mod:module_info/{0,1} in the debugger.
2011-08-16Remove the special handling of spawn BIFsBjörn Gustavsson
BIFs that spawn new processes once upon a time needed/benefited from special handling, but now they are handled in exactly the same way as an unsafe BIF (except for a bug in the handling of the return value trace). Therefore, treat spawn BIFs as unsafe BIFs.
2011-08-16Remove BIFs that no longer exist from dbg_iload:bif_type/1Björn Gustavsson
2011-08-16Handle all guard BIFs as safe in function bodiesBjörn Gustavsson
Make sure that all guards BIFs are handled as safe BIFs in function bodies. BIFs in guards are already handled as safe. (self/0 is not safe, but it is already specially handled.)
2011-08-16Remove support for erlang:fault/{1,2}Björn Gustavsson
Since erlang:fault/{1,2} is no longer supported in the run-time system (it was removed several releases ago), there is no need to still support it in the debugger.

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.
2011-08-08pcre: Rename Makefile.in to pcre.mk and include itBjörn Gustavsson
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.

2011-08-08megaco/src/flex/Makefile.in: Support parallel makeBjörn Gustavsson
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.
2011-08-08*/c_src/Makefile*: Support parallel makeBjörn Gustavsson
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. 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.
