Clifford Wolf f67ec1b235 Do not leak file descriptors in cover.cc 
Signed-off-by: Clifford Wolf <clifford@clifford.at>
 2019-05-15 13:51:02 +02:00
Henner Zeller 5e443a5d0d Fix two instances of integer-assignment to string. 
o In cover.cc, the int-result of mkstemps() was assigned to a string
  and silently interpreted as a single-character filename with a funny
  value. Fix with the intent: assign the filename.
o in libparse.cc, an int was assigned to a string, but depending on
  visible constructors, this is ambiguous. Explicitly cast this to
  a char.

whitequark a342d6db49 bugpoint: new pass. 
A typical use of `bugpoint` would involve a script with a pass under
test, e.g.:

    flowmap -relax -optarea 100

and would be invoked as:

    bugpoint -yosys ./yosys -script flowmap.ys -clean -cells

This replaces the current design with the minimal design that still
crashes the `flowmap.ys` script.

`bugpoint` can also be used to perform generic design minimization
using `select`, e.g. the following script:

    select i:* %x t:$_MUX_ %i -assert-max 0

would remove all parts of the design except for an unbroken path from
an input to an output port that goes through exactly one $_MUX_ cell.
(The condition is inverted.)

whitequark efa278e232 Fix typographical and grammatical errors and inconsistencies. 
The initial list of hits was generated with the codespell command
below, and each hit was evaluated and fixed manually while taking
context into consideration.

    DIRS="kernel/ frontends/ backends/ passes/ techlibs/"
    DIRS="${DIRS} libs/ezsat/ libs/subcircuit"
    codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint

More hits were found by looking through comments and strings manually.
