[Bug 669912] Re: natty gcc-4.5 kernel (2.6.37-rc1) build failure
Hi Robert, Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux 669912 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message.

Hi Ricardo, Yeap, this patch fixes the issue i was seeing with building both 2.6.35 and 2.6.37-rc's in natty.. and no regressions on the old userspaces, (lenny/karmic).. I haven't seen a need for the 2nd one, AFLAGS_sleep44xx.o :=-Wa,-march=armv7-a$(plus_sec) as i don't have the omap4 power management stuff as you guys.. With the merge 2.6.38 merge on the horizon, we better get this in.. ;) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/669912 Title: natty gcc-4.5 kernel (2.6.37-rc1) build failure -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

My reading of this is that 'smc' isn't in the base Cortex-A profile but requires the security extensions present. I think this can be enabled using '-march=armv7-a+sec' or (preferably) adding '.arch_extension sec' to the assembly code. -- natty gcc-4.5 kernel (2.6.37-rc1) build failure https://bugs.launchpad.net/bugs/669912 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Matthias, Thank you for taking some time to look at this.. Versions: gcc-4.5: gcc version 4.5.1 (Ubuntu/Linaro 4.5.1-9ubuntu1) gcc-4.4: gcc version 4.4.5 (Ubuntu/Linaro 4.4.5-7ubuntu1) as: GNU assembler version 2.20.90 So grepping the (arch/arm/Makfile) there's one occurance of 'mimplicit- it', and it's in the build kernel in thumb2 mode config which i usually don't enable.. ifeq ($(CONFIG_THUMB2_KERNEL),y) AFLAGS_AUTOIT :=$(call as-option,-Wa$(comma)-mimplicit-it=always,-Wa$(comma)-mauto-it) AFLAGS_NOWARN :=$(call as-option,-Wa$(comma)-mno-warn-deprecated,-Wa$(comma)-W) CFLAGS_THUMB2 :=-mthumb $(AFLAGS_AUTOIT) $(AFLAGS_NOWARN) AFLAGS_THUMB2 :=$(CFLAGS_THUMB2) -Wa$(comma)-mthumb endif So with that config enabled, it fails much sooner at: AS arch/arm/nwfpe/entry.o arch/arm/nwfpe/entry.S: Assembler messages: arch/arm/nwfpe/entry.S:96: Error: cannot use post-indexing with this instruction -- `ldrt r6,[r5],#4' make[1]: *** [arch/arm/nwfpe/entry.o] Error 1 make: *** [arch/arm/nwfpe] Error 2 So playing around with different things, i forced gcc-4.4 over gcc-4.5 in the kernel Makfile with: HOSTCC = gcc-4.4 HOSTCXX = g++-4.4 and it still fails...
