[PATCH, V2 8/9] NEWS: sframe: mention new semantics for SFrame FDE function start addr

[Indu Bhagat]

The SFrame FDE's function start address is always emitted as follows by
GAS and ld:  it is the offset of the start PC of the respective function
from the FDE field itself.

GAS and ld will emit a flag SFRAME_F_FDE_FUNC_START_ADDR_PCREL set to 1
when emitting the field in this encoding.

binutils/
	* NEWS: Announce the change of encoding for SFrame FDE func
	start addr field.

+* For SFrame stack trace format, the function start address in each SFrame FDE
+  has a changed encoding:  The 32-bit signed integer now holds the offset of
+  the start PC of the associated function from the sfde_func_start_address
+  field itself (instead of the earlier where it was the offset from the start
+  of the SFrame section itself).  All SFrame sections generated by gas and ld
+  generate the new encoding by default, with the (new) flag set:
+  SFRAME_F_FDE_FUNC_START_ADDR_PCREL to indicate the changed encoding.
+
+  Relocatable SFrame links are now fixed.
+
 * For RISC-V dis-assembler, the definition of mapping symbol $x is changed,
   so the file needs to be rebuilt since 2.45 once used .option arch directives.
