Bug ID: 64245
Summary: libgcc for msp430 depends on unreleased binutils
feature
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: dg at cowlark dot com
When building gcc for the msp430 as a cross compiler, configure attempts to
compile this as a test:
---
int main() { return 0; }
---
This turns into the following assembler (edited down):
---snip---
main:
.LFB0:
.loc 1 7 0
MOV.W #0, R12
.refsym __crt0_call_exit
RET
---snip---
Unfortunately the .refsym pseudoinstruction was added to binutils in January
2014 (AFAICT, here: http://comments.gmane.org/gmane.comp.gnu.binutils/64683),
and there hasn't been a binutils release since then --- the latest binutils,
2.24, was released late 2013 and doesn't have this feature, which means that
the MSP430 target can't actually be used with a released version of binutils.
For reference, the command line used to build the above code was:
/home/dg/src/gcc-4.9.2-objs/./gcc/xgcc -B/home/dg/src/gcc-4.9.2-objs/./gcc/
-B/usr/local/msp430/bin/ -B/usr/local/msp430/lib/ -isystem
/usr/local/msp430/include -isystem /usr/local/msp430/sys-include -S -g -O2
/tmp/test.c
