+Release 1.5
+=========
+
+- Support for "goto" in the source language Clight.
+
+- Added small-step semantics for Clight.
+
+- Traces for diverging executions are now uniquely defined;
+ tightened semantic preservation results accordingly.
+
+- Fixed spurious compile-time error on Clight statements of the form
+ "x = f(...)" where x is a global variable.
+
+- Fixed spurious compile-time error on Clight initializers where
+ the initial value is the result of a floating-point computation
+ (e.g. "double x = 3.14159 / 2;").
+
+- Simplified the interface of the generic dataflow solver.
+
+- Reduced running time and memory requirements for the constant propagation
+ pass.
+
+- Improved the implementation of George and Appel's graph coloring heuristic:
+ runs faster, produces better results.
+
+- Revised the implementation of branch tunneling.
+
+- Improved modularization between processor-dependent and
+ processor-independent parts.
+

The subset of the C language accepted by Compcert is quite large.
The main features of C that are not supported are:
- The "long long" and "long double" types.
- - The "goto" statement, and non-structured forms of the "switch" statement.
+ - Non-structured forms of the "switch" statement (Duff's device).
- Variable-argument functions.
The "ccomp" command will issue errors and diagnostics if it encounters
a C construct that it cannot process.
