Stephen Williams 04bdfbccee Add %cmpi/s and %cmpi/u instructions for performance
These bypass the vec4 stack in some common cases, saving instructions
and vec4 manipulations.

Also, minor improvement to the %flag/set/vec4 statement.

Kill a few warnings.

Stephen Williams aadd67cd3b Some instructions can do stack manipultations in place.
By doing some stack manipulations in place, certain instructions
can eliminate, or optimize, vector copies.

all assignments to a vector property will get the size right.

Cary R c5e0507941 Fix the modpath edge and vpi_put_delay() code
The code to get the correct modpath delay for a given edge had the X and Z
entries swapped.

When putting a delay from the VPI the 2 delay to twelve delay mapping was
incorrect and the to/from X delays were also not being calculated correctly.

Stephen Williams 98799ff7fa Allow class properties to be arrayed.
This adds the runtime support for class properties that are classes
to be arrayed. Add a means to define the dimensions of a property
in the vvp format, and add functions for setting/extracting elements
of a property.

Stephen Williams dec4cd5071 Handle arrays of class objects.
This goes all the way down to the vvp level, where we create support
for arrays of objects, generate the new code in the -tvvp code
generator, and elaborate the arrays in the first place.

Stephen Williams c9ff48bd4e Add support for dynamic array/queue "last" index ($)
Internally, treat the "$" as a special expression type that takes
as an argument the signal that is being indexed. In the vvp target,
use the $last system function to implement this.

Stephen Williams da63ef02d4 Implement the size method for queues.
This works by translating it to a $size() system function call.
The $size function is already implemented for dynamic queues and
it is easy enough to expand it for queues.

Nothing actually useful happens here, but the declarations
are functional.

Cary R d6b6b76015 Update header files to use a more standard name to prevent rereading
This is from github report #16. There are likely a few more issues

Stephen Williams b991a991a7 Implement vpi_handle(vpiLeft/RightRange, ...) for signals.
This returns a constant object that can be treated like an
expression, so following the letter of the LRM.

Stephen Williams 515137c8c7 Imlement vpi_handle(vpiScope, 0) for NULL handles
This is not part of the standard, but it convenient, and may be
used by the libveriuser to implement some bits of PLI1.
2014-07-14 17:15:16 -07:00
Stephen Williams d5fb0f4344 Handle some tricky conditions assignments to parts.
When for example assigning to foo[<x>] within a contitional, and
doing synthesis, we need to create a NetSubstitute device to manage
the l-value bit selects.

Larry Doolittle 850d8c3ee9 Eliminate a few more easy warnings
Testing with 32-bit clang 3.3, with additional compiler flags
 -Wsign-compare -Wundef
this patch eliminates the following warnings:

config.h💯6: warning: 'UINT64_T_AND_ULONG_SAME' is not defined, evaluates to 0 [-Wundef]
vcd_priv2.cc:233:12: warning: duplicate 'extern' declaration specifier [-Wduplicate-decl-specifier]
parse.cc:6496:9: warning: comparison of 0 <= unsigned expression is always true [-Wtautological-compare]
parse.cc:6499:13: warning: comparison of 0 <= unsigned expression is always true [-Wtautological-compare]
parse.cc:6502:9: warning: comparison of 0 <= unsigned expression is always true [-Wtautological-compare]
parse.cc:6510:53: warning: comparison of integers of different signs: 'const unsigned int' and 'int' [-Wsign-compare]

Changing the vlltype elements from unsigned to int reconciles their
type with the native bison YYLTYPE structure.

Larry Doolittle e221a8ced9 Rearrange compiler warning flags
Before this patch, WARNING_FLAGS applied to both C and C++,
and WARNING_FLAGS_CXX applied to C++ only.
This patch adds a WARNING_FLAGS_CC that applies to C only.
That change should be generally useful; in particular the C
code is almost ready for -Wstrict-prototypes, which does not
apply to C++.

-Wextra (or -W) used to only apply to C++ via WARNING_FLAGS_CXX.
This patch moves it to WARNING_FLAGS, to apply to both C and C++.
Unfortunately, that triggers a ton of warnings.

For now, cover most of the new warnings up by adding
-Wno-unused -Wno-sign-compare -Wno-type-limits
to WARNING_FLAGS_CC.  In the long run, I want to change the C coding
style, and take off these disable-warning flags.  But those changes
can dribble in as separate commits; this patch is big enough already.

Actually fix a couple missing-field-initializers in libveriuser/veriusertfs.c.

Larry Doolittle 6ebb57195b Fuss with C function prototypes
119 formal void parameters added to keep -Wstrict-prototypes happy.
Process found one real missing prototype in vpi/vcd_priv.h:
EXTERN void vcd_names_delete(struct vcd_names_list_s*tab);
8 such warnings left, all in Tony's code

Stephen Williams f8dc430fe5 Add synthesis support for casez statements.
This generates an EQZ LPM device that carries the case-z-ness to
the code generator.

Also add to the vvp code generator support for the EQZ device so
that the synthesis results can be simulated.

Account for the wildcard devices in the sizer.
