-Subject: [PATCH] Compute DW_FORM_block length correctly; also fixes #15068
-
-Before this patch, the pprUnwindwExpr function computed the length of
-by the following assembly fragment:
-
-	.uleb128 1f-.-1
-	<expression data>
-1:
-
-That is, to compute the length, it takes the difference of the label 1
-and the address of the .uleb128 directive, and subtracts 1.
-
-In #15068 it was reported that `as` from binutils 4.30 has trouble with
-evaluating the `.` part of the expression. However, there is actually a
-problem with the expression, if the length of the data ever becomes
-larger than 128: In that case, the .uleb128 directive will emit more
-than 1 byte, and the computed length will be wrong.
-
-The present patch changes the assembly fragment to use two labels,
-which fixes both these problems.
-
-	.uleb128 2f-1f
