+	[BZ #2749]
+	* soft-fp/op-4.h (__FP_FRAC_SUB_3, __FP_FRAC_SUB_4): Correct borrow
+	handling for high words.
+	* soft-fp/op-common.h (_FP_OVERFLOW_SEMIRAW): Always set inexact
+	and overflow for infinity.
+	(_FP_PACK_SEMIRAW): Update comment.  Do not round if NaN or Inf.
+
+	* math/basic-test.c (truncdfsf_test): New function.
+	[!NO_LONG_DOUBLE] (trunctfsf_test): New function.
+	[!NO_LONG_DOUBLE] (trunctfdf_test): New function.
+	Change main() to do_test. Define TEST_FUNCTION. Include test-skeleton.c. 
+	(do_test): Run new tests.
+
+2007-01-15  Jakub Jelinek  <jakub@redhat.com>
+
+	* soft-fp/op-common.h (FP_TRUNC): When truncating a NaN, clear
+	workbits in semi-raw fraction.
