GNU Arm Embedded Toolchain

GCC m68k pc-relative

Asked by WOJTOWKI

Hello,
I was using a Microtek toolchain to generate an executable binary with relocatable code (pc-relative) and data from a fixed address (Absolute data). Today, this toolchain does not work on Windows 7 64 bits. The idea is to replace Microtek toolchain for 68000 with the GNU toolchain (GCC 4.8.0).

But I can not find the same options on the gcc compiler:

Microtec compiler "MCC68K" with:
"-Mcp": Directs the compiler to use PC-relative addressing for all code references.
"-Mda": Directs the compiler to use absolute addressing for all data references.

Gcc (m68k-elf-gcc) with:
-mpcrel

Unable to build with gcc relocatable code with no relocatable data as the Microteck compiler. With "-mpcrel", all is relocatable (code and data).

do you have an idea?

Sorry for my bad english.

Thanks.

I don't get it. If you are seeking support for non-ARM target, I'm afraid I
have no expertise to help. This tools only work for ARM targets.
