Bug 602390 - New file for SH4 auto-generated code (r+rreitmai) [Cédric VINCENT]
. . attachment 493930 - SH4: use non-numeric type for Register & move auto-generated code-generator back to a separated file. . Bug 599251 introduced the non-numeric Register type. This back-end doesn't use it yet. It should. See the i386/X64 back-ends for examples. --HG-- extra : convert_revision : eb3a73807a9c8b2cafe10908710f9cb2467d090d
