| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch should support things like `define foo(a, b = 3, c) a+b+c `foo(1, ,2) which will evaluate to 1+3+2. It also spots mistakes like `foo(1) (the 3rd argument doesn't have a default value, so a call site is required to set it). Most of the patch is a simple parser for the format in preproc.cc, but I've also taken the opportunity to wrap up the "name -> definition" map in a type, rather than use multiple std::map's. Since this type needs to be visible to code that touches defines, I've pulled it (and the frontend_verilog_preproc declaration) out into a new file at frontends/verilog/preproc.h and included that where necessary. Finally, the patch adds a few tests in tests/various to check that we are parsing everything correctly.

| * | ast: avoid intermediate wires/assigns when lowering to AST_MEMINIT.whitequark2020-02-071-65/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, every initial assignment to a memory generated two wires and four assigns in a process. For unknown reasons (I did not investigate), large amounts of assigns cause quadratic slowdown later in the AST frontend, in processAst/removeSignalFromCaseTree. As a consequence, common and reasonable Verilog code, such as: reg [`WIDTH:0] mem [0:`DEPTH]; integer i; initial for (i = 0; i <= `DEPTH; i++) mem[i] = 0; took extremely long time to be processed; around 80 s for a 8-wide, 8192-deep memory. After this commit, initial assignments where address and/or data are constant (after `generate`) do not incur the cost of intermediate wires; expressions like `mem[i+1]=i^(i<<1)` are considered constant. This results in speedups of orders of magnitude for common memory sizes; it now takes merely 0.4 s to process a 8-wide, 8192-deep memory, and only 5.8 s to process a 8-wide, 131072-deep one. As a bonus, this change also results in nontrivial speedups later in the synthesis pipeline, since pass sequencing issues meant that all of these intermediate wires were subject to transformations such as width reduction, even though they existed solely to be constant folded away in `memory_collect`.
