From 6550162200b40d1e725167f8a617255c42b57552 Mon Sep 17 00:00:00 2001 From: Chris Zankel Date: Tue, 13 Nov 2012 15:16:36 -0800 Subject: xtensa: add config option to disable linker relaxation The default linker behavior is to optimize identical literal values and remove unnecessary overhead from assembler-generated "longcall" sequences to reduce code size. Provide an option to disable this behavior to improve compile time.
