[Bug binutils/12844] New: TARGET is undefined in bucomm.c
http://sourceware.org/bugzilla/show_bug.cgi?id=12844 Summary: TARGET is undefined in bucomm.c Product: binutils Version: 2.21 Status: NEW Severity: normal Priority: P2 Component: binutils AssignedTo: unassig...@sources.redhat.com ReportedBy: hazelnu...@gmail.com I'm running Kubuntu 11.04 on x86_64 and have downloaded binutils-2.21 and after untaring I run: mkdir build cd build ../configure make and I get this error: gcc -DHAVE_CONFIG_H -I. -I../../binutils -I. -I../../binutils -I../bfd -I../../binutils/../bfd -I../../binutils/../include -DLOCALEDIR="\"/usr/local/share/locale\"" -Dbin_dummy_emulation=bin_vanilla_emulation -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Werror -g -O2 -MT bucomm.o -MD -MP -MF .deps/bucomm.Tpo -c -o bucomm.o ../../binutils/bucomm.c ../../binutils/bucomm.c: In function ‘set_default_bfd_target’: ../../binutils/bucomm.c:160:24: error: ‘TARGET’ undeclared (first use in this function) ../../binutils/bucomm.c:160:24: note: each undeclared identifier is reported only once for each function it appears in make[4]: *** [bucomm.o] Error 1 The same thing happens in the daily snapshot of binutils. I have not found this error anywhere via Google, and the source simply says: /* The macro TARGET is defined by Makefile. */ const char *target = TARGET; Obviously, TARGET is not getting defined, but I don't know why. I have tried setting the --target configure option (--target=arm-eabi, in my particular case), but this does not fix it. It would be great to know what I'm doing wrong or if this is a bug. -- 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 https://lists.gnu.org/mailman/listinfo/bug-binutils
[Bug gas/13215] New: ARM Cortex M3 strexh strexb instructions with same registers generates error
http://sourceware.org/bugzilla/show_bug.cgi?id=13215 Bug #: 13215 Summary: ARM Cortex M3 strexh strexb instructions with same registers generates error Product: binutils Version: 2.21 Status: NEW Severity: critical Priority: P2 Component: gas AssignedTo: unassig...@sources.redhat.com ReportedBy: hazelnu...@gmail.com Classification: Unclassified Created attachment 5939 --> http://sourceware.org/bugzilla/attachment.cgi?id=5939 example of ARM provided code that makes use of strexh strexb with same registers In gas version 2.21.53, when compiling for the Cortex-M3 with -mcpu=cortex-m3 -march=armv7-m, the following instructions generate assembler errors: strexh r0, r0, [r1] strexb r0, r0, [r1] The error messages are: Error: registers may not be the same -- `strexh r0,r0,[r1]' Error: registers may not be the same -- `strexb r0,r0,[r1]' However, according to the ARM documentation of STREX for the Cortex M3 [0], only the word sized (32-bit) version of the instruction strex has the restriction that the three registers be unique: for STREX, Rd must be different from both Rt and Rn This problem shows up, for example, when trying to compile vendor provided peripheral libraries that make use of CMSIS. In particular, the core_cm3.[ch] of CMSIS v1.3, and core_cmInstr.h of CMSIS v2.0 have all of these instructions. Curiously, even strex r0, r0, [r1] shows up in CMSIS, even though this is explicitly restricted in [0]. So perhaps even some of the CMSIS code is breaking the specification of the ARM documentation, not sure.

[Bug gas/13215] ARM Cortex M3 strexh strexb instructions with same registers generates error
http://sourceware.org/bugzilla/show_bug.cgi?id=13215 Luke Peterson changed: What|Removed |Added Status|NEW |RESOLVED Resolution||INVALID --- Comment #1 from Luke Peterson 2011-09-22 16:22:03 UTC --- A closer read of the ARMv7m reference manual confirms that for any of the strex instructions (word, half word, byte), if the register are the same, the result is undefined. So James Greenhalgh's patch is correct, and this bug is invalid. -- 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 https://lists.gnu.org/mailman/listinfo/bug-binutils
