re PR tree-optimization/83198 (ICE in format_floating, at gimple-ssa-sprintf.c:1900)
PR tree-optimization/83198
* gimple-ssa-sprintf.c (format_floating): Set type solely based on
dir.modifier, regardless of TREE_TYPE (arg). Assume non-REAL_CST
value if arg is a REAL_CST with incompatible type.
* gcc.dg/pr83198.c: New test.
* gcc.dg/tree-ssa/pr83198.c: New test.
