expr.c (generate_name): Name prefix changed to avoid clashes with assembler temp labels.
1999-01-13 Andrew Haley <aph@cygnus.com>
* expr.c (generate_name): Name prefix changed to avoid clashes
with assembler temp labels.
* parse.y (patch_synchronized_statement): Set TREE_SIDE_EFFECTS on
MODIFY_EXPR. Without this, code for the assignement may not be
generated at all and the synchronized statement will read an
uninitialized variable.
