George Koehler	f1304e1a3c	Use extended mnemonics and ha16/lo16. ... Remove wrong comment: that's a right shift, not a left shift.	2018-01-11 20:04:27 -05:00
George Koehler	5b69777647	Rename our pseudo-opcode 'la' to 'li32'. ... GNU as has "la %r4,8(%r3)" as an alias for "addi %r4,%r3,8", meaning to load the address of the thing at 8(%r3). Our 'la', now 'li32', makes an addis/ori pair to load an immediate 32-bit value. For example, "li32 r4,23456789" loads a big number.	2016-09-18 17:03:23 -04:00
David Given	80cb6ba927	Eliminate the RELOH2 relocation, as it never worked --- the address would be ... calculated incorrectly because of overflow errors. Replace it with an extended RELOPPC relocation which understands addis/ori pairs; add an la pseudoop to the assembler which generates these and the appropriate relocation. Make good. --HG-- branch : dtrg-experimental-powerpc-branch	2016-09-17 12:43:15 +02:00
