Fix a bug caused by zs's recent change to runtime/mercury_stack_trace.{h,c}:
library/require.m:
library/math.m:
Update calls to MR_dump_stack() to pass as the new
`include_trace_data' argument the value `FALSE'.
Estimated hours taken: 30
Changes to compile the compiler using compilers other then gcc. Tested
on 'cc -std1', 'cc -std1 -migrate' on the alphas, 'cc' and 'lcc' on the
sparcs.
boehm_gc/linux_threads.c:
Ensure that the compilation unit isn't empty by always #including at
least on file.
compiler/llds_out.m:
Remove all remaining occurences of (const Word *).
compiler/mercury_compile.m:
Call transform_llds.
compiler/options.m:
Add the option max_jump_table_size. This option is needed because
lcc barfs when the jump_table for computed gotos size is over 128.
compiler/transform_llds.m:
Transform computed_gotos whose table size is over
max_jump_table_size to binary search down to computed gotos whose
table size is less then or equal to max_jump_table_size.
doc/user_guide.texi:
Document --max-jump-table-size.
library/benchmarking.m:
library/math.m:
library/private_builtin.m:
library/std_util.m:
s/\\n/\\\\n/g so that we don't get line breaks in string constants.
library/io.m:
Change an LVALUE_CAST to type Word as RHS of the expression gets
cast to type Word.
scripts/mgnuc.in:
lcc gets called with "-w" flag to avoid spurious warnings. Also if
--no-ansi is defined pass "-D__EXTENSIONS__" to the compiler to
ensure that all of the header files are read.
trace/mercury_trace_internal.c:
Add a cast to (Word *) because LHS of the expression has type (Word *)
Estimated hours taken: 0.4
library/math.m:
Include mercury_trace.h since we use MR_trace_report (this
fixes a compiler warning).
A couple of minor documentation fixes/enhancements.
Estimated hours taken: 3
library/math.m:
library/float.m:
Addition of four new system constants (float__radix,
float__mantissa_digits, float__min_exponent and
float__max_exponent) plus predicate equivalents. Also
added in some extra documentation for the other constants.
Rename floating point constants using the C coding standard
way (ML_*).
Put code for mathematical domain checking inside
`#ifndef ML_OMIT_MATH_DOMAIN_CHECKS', so that the user
can disable domain checking. (Note: This is actually safe,
since the combination of floating point hardware and -lm
should do all these checks for you.)
NEWS:
Mention the above changes.
Estimated hours taken: 1.5
Improve the multi-threaded execution support.
runtime/mercury_context.{c,h}:
Move the code for runnext from the .h file to the .c file -
it is reasonably large (in the thread_safe grades) so avoiding
the duplication is handy. It also makes debugging much easier!
Also, make scheduling a context as runnable append it to the
end of the runqueue, rather than consing it to the front. This
yeilds more useful behaviour for concurrent code that wants to
yeild in favour of any other runnable context.
library/math.m:
library/string.m:
library/io.m:
Add thread_safe to the flags for a whole bunch of predicates and
functions that are thread-safe.
Estimated hours taken: 0.5
library/*.m:
Convert
:- pragma(c_code, ...
to
:- pragma c_code(...
and introduce will_not_call_mercury in places where it is implicit
(this is in preparation for changing the default to may_call_mercury).
Estimated hours taken: 0.1
library/math.m:
Fix a cut-and-paste bug reported by Dan Hazel
<d.hazel@mailbox.uq.edu.au>: Mercury's acos/1 was
calling C's asin() instead of acos().
Estimated hours taken: 0.5
library/*.m:
compiler/*.m:
Undo Zoltan's bogus update of all the copyright dates.
The dates in the copyright header should reflect the years
in which the file was modified (and no, changes to the
copyright header itself don't count as modifications).
Estimated hours taken: 3
Enable --warn-interface-imports by default. This was turned off while
list and term were defined in mercury_builtin.m, since it caused many
warnings.
Fix all the unused interface imports that have been added since then.
compiler/options.m:
Enable --warn-interface-imports by default.
compiler/module_qual.m:
Fix formatting inconsistencies with module names in warning
messages. (".m" was not appended to module names if there was
only one module).
compiler/*.m:
library/*.m:
tests/invalid/type_loop.m:
tests/warnings/*.m:
Remove usused interface imports, or move them into
implementation (mostly bool, list and std_util).
Estimated hours taken: 1
Changed mathematics predicates into functions, which are generally
more convenient.
All the original predicates have been left in but have been marked
obsolete.
mercury/library/math.m
Estimated hours taken: 4
library/Mmake:
Change rule for libmercury.opt.a so that it doesn't recompile
everything when anything changes. Add a rule for installing it.
library/*.m:
Use pragma(c_code, "...") rather than pragma(c_header_code, "...")
for C code that is definitions not declarations, so that it works
with --split-c-files.
Estimated hours taken: 24
Move the C implementation of various builtins from the `runtime' directory
to inside pragma(c_code) declarations in the `library' directory sources.
library/{io,string,require,std_util,mercury_builtin}.m:
Add lots of pragma(c_code) and pragma(c_header_code) declarations.
Also a few other miscellaneous changes.
library/list.m:
Fix a bug in the as yet unused list__merge_sort.
library/io.m:
Combine io__do_open_{input,output,append} into a single
predicate io__do_open.
library/std_util.m:
Fix the implementation of report_statistics so that it gives
useful information when using conservative garbage collection.
library/*.m:
Improve the documentation.
Add a "Stability: low/medium/high" comment to all modules,
which describes the stability of the interface to that module.
ops.m:
Add `:' as an infix operator.
require.m:
Implement require/1, since higher-order predicates now work.
term.m:
Use the type `comparison_result' from mercury_builtin.m,
rather than defining an identical type `comparison'.
