* | Fix two instances of integer-assignment to string.Henner Zeller2019-05-141-1/+2
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)
