398730 - Remove default suffix rules from rules.mk, and some fixes to help automated rewriting

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Benjamin Smedberg]

Attachment: rules.mk changes for automatic rewriting, rev. 1

We can help the automated rewriting effort by changing a little bit of rules.mk:

1) Disable all the default rules all the time... this should improve build speed (perhaps significantly!) as well as prevent some of the default %.o: %.s from ever being applied

2) Disable the assembly-source rule unless a makefile explicitly specifies assembly files. This will help because automated rewriting leaves intermediate .ii and .s files around and rules.mk gets confused about what it's supposed to be building.

3) Add the intermediate targets to the garbage. This will remove all the intermediate .ii and .s files in "make clean" so that you can do full rebuilds of specific directories

I really want this for moz2, but I don't see any reason it can't land in CVS for 1.9

Again, this is very low-risk assuming the tboxes don't turn red.
