This commit makes the code (mostly) C99-compatible, enabling to compile
it without the -Wno-error=implicit-function-declaration flag. This
way, Magic becomes usable on arm64 architectures, specifically on Apple
computers with M1/M2 SoC.
traditionally been kept for backwards compatibility. However, the
operation of "ext2spice" and "ext2sim" as separate programs has
become extremely difficult to maintain, and so it has been dropped
in favor of folding both into the program as commands, as was done
a long time ago in the Tcl/Tk version.
presented on the command line, then all following arguments are
assumed to be arguments of the script and not additional input
to be processed by magic. This allows arguments to be passed to
scripts passed to magic on the command line.
If exit is called in a TCL script that is executed at startup, the libc
exit() function is called directly and we don't get a chance to reset
the terminal. We return to the shell with echo off, and have to run
"reset". A simple example:
echo exit > test.tcl
magic -noconsole -dnull test.tcl
There are a few ways we could solve this. We could register an exit
handler using atexit(). Here I use Tcl_SetExitProc() to register a
callback with the TCL interpreter.
read". While "lef read" normally annotates existing layout, this
option ensures that no additional cells are created from macros in
the input LEF file. (2) Added a check on the "Input off lambda grid"
warning during CIF/GDS input such that it is not repeated once issued,
as it tends to be output many times when it occurs.
enabling the "plow" command. At this time, however, not all
rules are being implemented correctly given the numerous changes
to the DRC handling since the last time "plow" was working. Fixes
are ongoing.
development had been halted since it was first created back in April.
Version 8.2 is now the official development version, with the first
development push to create a Cairo graphics interface.
