Eddie Hung 164dd0f6b2 kernel: Use constids.inc for global/constant IdStrings 2020-04-02 07:14:08 -07:00

Merge pull request #1845 from YosysHQ/eddie/kernel_speedup 
kernel: speedup by using more pass-by-const-ref

Eddie Hung 348e892314 kernel: pass-by-value into Design::scratchpad_set_string() too 2020-03-27 12:21:09 -07:00
Rupert Swarbrick 044ca9dde4 Add support for SystemVerilog-style `define to Verilog frontend 
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.

whitequark e97e33d00d kernel: require \B_SIGNED=0 on $shl, $sshl, $shr, $sshr. 
Before this commit, these cells would accept any \B_SIGNED and in
case of \B_SIGNED=1, would still treat the \B input as unsigned.

Also fix the Verilog frontend to never emit such constructs.

Henner Zeller 8c2b4f0a50 Avoid work in replace() if rules empty. 
This speeds up processing when number of bits are large but there
is actually nothing to replace. Adresses part of #1382.
