That more or less sorted things out - the exact code writing beyond the allocated area is clear (line 1083 in gas/app.c), but how it got there I don't quite follow. I have included the backtrace below, and as far as I can see it would require that the character 'e' was considered a separator between parallel insns and screwing up the value of to just before that.

[LV] Status of the toolchain build scripts?
by Mikkel Lauritsen 19 Jun '07

19 Jun '07

Hi all, is there any chance of getting a quick status on the toolchain build scripts? I have decided to once again delurk and try to see if I can extract enough free time to do some hacking, but getting the initial toolchain going is slightly cumbersome :-) Aside from a couple of small and easily fixable bugs caused by things being outdated (name of CVS server as mentioned on How-To-Get-Started web page; version of MPFR wget'ed by scripts) I have bumped into the more serious issue that the vax-dec-linux-uclibc target tuple is not supported by the GCC 4.3.0 that the scripts check out. Is this as intended, have I screwed up in obtaining some patches or is there another reason? Any suggestions for how to get around this problem would be much appreciated as my Vaxen are itching for a freshly built kernel... Best regards and thanks Mikkel Lauritsen _______________________________________________ Linux-Vax mailing list Linux-Vax(a)pergamentum.com http://www.pergamentum.com/mailman/listinfo/linux-vax

[LV] The Linux binutils 2.17.50.0.17 is released
by H. J. Lu 18 Jun '07

18 Jun '07

This is the beta release of binutils 2.17.50.0.17 for Linux, which is based on binutils 2007 0615 in CVS on sourceware.org plus various changes. It is purely for Linux. All relevant patches in patches have been applied to the source tree. You can take a look at patches/README to see what have been applied and in what order they have been applied. Starting from the 2.17.50.0.4 release, the default output section LMA (load memory address) has changed for allocatable sections from being equal to VMA (virtual memory address), to keeping the difference between LMA and VMA the same as the previous output section in the same region. For data.init_task : { *(.data.init_task) } LMA of .data.init_task section is equal to its VMA with the old linker. With the new linker, it depends on the previous output section. You can use data.init_task : AT (ADDR(.data.init_task)) { *(.data.init_task) } to ensure that LMA of .data.init_task section is always equal to its VMA. The linker script in the older 2.6 x86-64 kernel depends on the old behavior. You can add AT (ADDR(section)) to force LMA of data.init_task section equal to its VMA. It will work with both old and new linkers. The x86-64 kernel linker script in kernel 2.6.13 and above is OK. The new x86_64 assembler no longer accepts monitor %eax,%ecx,%edx You should use monitor %rax,%ecx,%edx or monitor which works with both old and new x86_64 assemblers. They should generate the same opcode. The new i386/x86_64 assemblers no longer accept instructions for moving between a segment register and a 32bit memory location, i.e., movl (%eax),%ds movl %ds,(%eax) To generate instructions for moving between a segment register and a 16bit memory location without the 16bit operand size prefix, 0x66, mov (%eax),%ds mov %ds,(%eax) should be used. It will work with both new and old assemblers. The assembler starting from 2.16.90.0.1 will also support movw (%eax),%ds movw %ds,(%eax) without the 0x66 prefix. Patches for 2.4 and 2.6 Linux kernels are available at http://www.kernel.org/pub/linux/devel/binutils/linux-2.4-seg-4.patch http://www.kernel.org/pub/linux/devel/binutils/linux-2.6-seg-5.patch The ia64 assembler is now defaulted to tune for Itanium 2 processors. To build a kernel for Itanium 1 processors, you will need to add ifeq ($(CONFIG_ITANIUM),y) CFLAGS += -Wa,-mtune=itanium1 AFLAGS += -Wa,-mtune=itanium1 endif to arch/ia64/Makefile in your kernel source tree.

[LV] TURBOchannel support -- success!
by Maciej W. Rozycki 09 Jun '07

09 Jun '07

Hello, The list seems to have been rather silent recently. But in case there are still readers out there I am pleased to announce initial success with porting TURBOchannel support to the VAXstation 4000/90 equipped with the DWCTX adapter. A moderately easy addition of this support has been enabled by the recent rewrite of the TURBOchannel bus support to the driver model which is as of 2.6.21-rc1 available upstream now. Here is a bootstrap log from my system using a PMAD-A Ethernet adapter for the interface used for NFS-root. This board uses PIO transactions only, but my experiments with some other boards show DMA works correctly as well. Unfortunately the DMA API is currently unsupported, so using a card like one of the DEFTA variations is not possible out of the box. Comments are welcome, especially ones to provide incentive for more work in this area. ;-) Maciej >>> show config KA49-A V1.0-006-V4.0 08-00-2B-30-96-D8 128MB DEVNBR DEVNAM INFO ------ -------- -------------------------- 1 NVR OK 2 LCSPX OK Highres 72Hz - 8 Plane 4Mpixel FB - V1.0 3 DZ OK 4 CACHE OK 5 MEM OK 128MB 0A,0B,0C,0D=16MB, 1E,1F,1G,1H=16MB 6 FPU OK 7 IT OK 8 SYS OK 9 NI OK 10 SCSI OK 6-INITR 11 AUD OK 13 TCA OK OPT PRS V1.0 >>> boot eza0 -EZA0 * ** Welcome to Linux on VAX ** * CPU type: KA49 SID: 0x13000202 SIDEX: 0x04010002 Boot Head.S loaded at address 0x00006600 rpb/bootr5/ap/sp 0x00000000 0x00000000 0x00000EC0 0x00006400 relocated at phys address 0x0010028A Starting VM Early console enabled Linux/VAX <linux-vax(a)pergamentum.com> RPB info: .l_pfncnt=0x0003fd6d, .l_vmb_version=0x13000100, .l_badpgs=0x00000000 Physical memory: 0x0003fd6d HW pagelets, 0x00007fad pages (130742KB) CPU type: KA49, SID: 0x13000202, SIDEX: 0x04010002 VM: mapped physical from 0x80000000 to 0x87fada00, iomap from 87fae000 VM: vmalloc from 0x8ffae000 to 0x903ae000 VM: ptemap from 0x903ae000 to 0x928ae000 for 64 processes Calling start_kernel()...
