Build System and Mach Environment
*
Starting with Bug 1746462
<https://bugzilla.mozilla.org/show_bug.cgi?id=1746462>you can use
the mold linker for linking Mozilla Firefox on most Linux
distributions. MacOS support will come shortly.
I tested "mold" for building C-C thunderbird.
I was impressed.
|The I/O speed during linking "libxul", the large libary, is near the
max bandwidth of my local disk setup (on a linux guest within VirtualBox
hosted under Windows 10).
I watched the xosview's disk I/O activity with amusement.
As is described in Bugzilla, then all of a sudden the multiple CPU's got
busy (I have assigned 7 vCPUs to my linux guest and 16GB of memory
assigned) and linking was over.
In contrast, with GNU gold which I have been using, I see prolonged I/O
not near the maximum bandwidth and single CPU getting busy during long
linking.
Of course, the linking is only a small portion of the whole build
process, but it *IS* a lengthy process.
This is a great work.
Keep the good work going!
