| * * Improved handling of registers used in assembler blocks. Assembler nodes ↵sergei2015-02-251-2/+5
| | | | | | | | | | | | | | | | | | no longer have lists of used registers attached to them. Instead, each specified register creates an allocation/deallocation pair and an additional tai_regalloc.markused item directly in the asmlist. This way, register lists are no longer limited to integer registers, and parsing no longer depends on paramanager to know which registers are volatile. If assembler block has no modified register list, it is still handled in pass2, by allocating all volatile registers (not only the integer ones as before). git-svn-id: http://svn.freepascal.org/svn/fpc/trunk@30011 3ad0048d-3df7-0310-abae-a5850022a9f2
