/* GP32 Linker Script v1.2 by Jeff F */
/* v1.0 - Original release */
/* v1.1 - Cleaned up and added MEMORY command */
/* v1.2 - DJWillis - Added propper .init and */
/* .fini for GCC 3.3.2 and above */
/* */
/* This file is released into the public domain */
/* for commercial or non-commercial use with no */
/* restrictions placed upon it. */
/* */
/* NOTE!!!: This linker script defines the RAM */
/* start addresses. In order for it to work */
/* properly, remove -Ttext and -Tbss linker */
/* options from your makefile if they are */
/* present. */
/* */
/* You can use the following to view section */
/* addresses in your .elf file: */
/* objdump -h file.elf */
/* */
/* Please note that empty sections may incorrectly*/
/* list the lma address as the vma address for */
/* some versions of objdump. */
OUTPUT_FORMAT("elf32-littlearm", "elf32-bigarm", "elf32-littlearm")
OUTPUT_ARCH(arm)
ENTRY(_start)
/* SEARCH_DIR(/bin/arm); */
/* Then use it like this: IWRAMHEAP */
/* The linker script function "var1 += var2;" sometimes */
/* reports incorrect values in the *.map file but the */
/* actual value it calculates is usually, if not always, */
/* correct. If you leave out the ". = ALIGN(4);" at the */
/* end of each section then the return value of SIZEOF() */
/* is sometimes incorrect and "var1 += var2;" appears to */
/* not work as well. "var1 += var2" style functions are */
/* avoided below as a result. */
/* The linker script MEMORY directive is not used here due */
/* to the fact that __text_start is not always a fixed value. */
