Changelog for sv2v-0.0.10

v0.0.10

Added support for assignments within expressions (e.g., x = ++y;)
Added support for excluding the conversion of unbased unsized literals (e.g., '1, 'x) via --exclude UnbasedUniszed
Added support for enumerated type ranges (e.g., enum { X[3:5] })
Added support for complex event expressions (e.g., @(x ^ y))
Added support for the SystemVerilog edge event
Added support for cycle delay ranges in assertion sequence expressions
Added support for procedural continuous assignments (assign/deassign and force/release)
Added conversion for do while loops
Added support for hierarchical calls to functions with no inputs
Added support for passing through DPI imports and exports
Added support for passing through functions with output ports
Extended applicability of simplified Yosys-compatible for loop elaboration

Certain errors raised during conversion now also provide hierarchical and approximate source location information to help locate the error

Fixed inadvertent design behavior changes caused by constant folding removing intentional width-extending operations such as + 0 and * 1
Fixed forced conversion to reg of data sensed in an edge-controlled procedural assignment
always_comb and always_latch now generate explicit sensitivity lists where necessary because of calls to functions which reference non-local data
Fixed signed struct fields being converted to unsigned expressions when accessed directly
Fixed conversion of casts using structs containing multi-dimensional fields
Fixed incorrect name resolution conflicts raised during interface inlining
Fixed handling of interface instances which shadow other declarations
Fixed names like <pkg>_<name> being shadowed by elaborated packages

Unsized number literals exceeding the maximum width of 32 bits (e.g., 'h1_ffff_ffff, 4294967296) are now truncated and produce a warning, rather than being silently extended
- Support for unsized number literals exceeding the standard-imposed 32-bit limit can be re-enabled with --oversized-numbers
Input source files are now decoded as UTF-8 on all platforms, with transcoding failures tolerated, enabling reading files encoded using other ASCII supersets (e.g., Latin-1)

Added support for non-ANSI style port declarations where the port declaration is separate from the corresponding net or variable declaration
Added support for typed value parameters declared in parameter port lists without explicitly providing a leading parameter or localparam marker
Added support for tasks and functions with implicit port directions
Added support for parameters which use a type-of as the data type
Added support for bare delay controls with real number delays
Added support for deferred immediate assertions

Explicitly-sized number literals with non-zero bits exceeding the given width (e.g., 1'b11, 3'sd8, 2'o7) are now truncated and produce a warning, rather than yielding a cryptic error
Number literals with leading zeroes which extend beyond the width of the literal (e.g., 1'b01, 'h0_FFFF_FFFF) now produce a warning
Non-positive integer size casts are now detected and forbidden
Negative indices in struct pattern literals are now detected and forbidden
Escaped vendor block comments in macro bodies are now tolerated
Illegal bit-selects and part-selects of scalar struct fields are now detected and forbidden, rather than yielding an internal assertion failure

Fixed parsing of sized ports with implicit directions
Fixed flattening of arrays used in nested ternary expressions
Fixed preprocessing of line comments which are neither preceded nor followed by whitespace except for the newline which terminates the comment
Fixed parsing of alternate spacings of @(*)
Fixed conversion of interface-based typedefs when used with explicit modports, unpacked arrays, or in designs with multi-dimensional instances
Fixed conversion of module-scoped references to modports
Fixed conversion of references to modports nested within types in expressions
Fixed assertion removal in verbose mode causing orphaned statements

Future releases will have complete change logs.
