2005-11-17 Jan Beulich <jbeulich@novell.com> * dw2gencfi.c (dot_cfi): Put argument parsing for cases DW_CFA_restore and DW_CFA_undefined in a loop.
2005-10-11This adjusts equate handling byNick Clifton1-1/+1
- allowing true forward references (which will always assume the referenced symbols have at the point of use) through the new .eqv pseudo-op and the new == operator - disallowing changing .equiv-generated equates (so that the protection this provides is both forward and backward) - snapshotting equates when their value gets changed so that previous uses don't get affected by the new value. - allowing expressions in places where absolute expressions (or register names) are needed which were not completely resolvable at the point of their definition but which are fully resolvable at the point of use In addition it fixes PR/288.
