1) Added a "*showmem" "wizard" command to get a dump of all memory
being used by tiles in the database.
2) Made a slight correction to the way magic detects exact overlap
of instances of the same cell. This probably does not make any
actual difference in practice.
3) Corrected an uninitialized variable in dbReComputeBboxFunc().
4) Changes DBSrCellPlaneArea() to use a static BPEnum variable, so
that it does not waste time allocating and freeing memory for
the same thing over and over again.
5) Corrected a memory leak in the tech file "extract" section that
loses memory every time the extraction style is changed.
6) Corrected the tile join routines to fix a bad memory leak in the
tile allocation and recovery---a fix which was mentioned in issue
#414 but which had not yet been implemented. This has now been
tested and confirmed to work.
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.
of an alias that defines only one type (which is treated like it
would be if it were declared on the same line as the original type
declaration), such that the alias name does not become the default
name for the layer (which is the one that ends up showing in the
title bar when hovering over the layer toolbar icon). Mainly the
problem showed up as "nwell" for the sky130A process appearing in the
toolbar as "allwellplane".
the path component of the use def was interpreted as being relative
to the parent when reading the cell def but not when writing,
resulting in paths being interpreted incorrectly.
