--- Comment #2 from Dan McDonald <dan at wellkeeper dot com> 2011-03-29 19:52:08 UTC --- Created attachment 5340 --> http://sourceware.org/bugzilla/attachment.cgi?id=5340 update ARM_AEXT_V7_ARM macro to include ARM_OS_EXT flag This also affects target arm-none-eabi. Like Claudio, I am also trying to compile FreeRTOS. It looks like the v7 processor profile (which the Cortex-M3 is an example of) neglects to mark the "os" extension as being available. I attached a diff against CVS that fixes this issue for me. The patch updates the ARM_AEXT_V7_ARM macro to also include the ARM_OS_EXT flag. I believe that all v7 processors have the SVC instruction (based on the v7-M and v7-AR reference manuals). $ echo 'svc 0' > /tmp/x.s $ arm-none-eabi-as -mcpu=cortex-m3 /tmp/x.s -o /tmp/x.o $ arm-none-eabi-objdump -d /tmp/x.o /tmp/x.o: file format elf32-littlearm Disassembly of section .text: 00000000 <.text>: 0: df00 svc 0 -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
