V7.50 USES TOO MUCH SPACE FOR FAR CONST DATA

Applies to: CX51 C Compiler

Answer


Information in this article applies to:


SYMPTOM

When I define data symbols as FAR CONST, the list file shows that the compiler has "allocated" twice as much space as necessary to hold that data.

CAUSE

There was an error in an early build of CX51.exe, v7.50. This caused all FAR CONST space to be allocated twice.

RESOLUTION

The attached file contains an updated version of CX51.exe. Download the .ZIP archive and unzip the enclosed file to C:KeilC51BIN.

STATUS

This problem is fixed in Version 8.00 of the Keil C51 tools.
