sparc

I asked a similar question, but I have some update which is really confusing me. Essentially, I want to link a number of object files with the linker as follows: /usr/ccs/bin/ld -o q -e start_master -dn -z defs -M ../../../mapfile.q {list of object files} I get the following error: Undefined first referenced symbol in file _memset reconf.o The interesting things is, that memset is not referenced in reconf.c and I also grep'ed the whole directory but there is also no reference in any of the other files to _memset. Therefore I am wondering why I get this error message from the linker, although

I am having some issues with a makefile I am creating for a school project. I am compiling and assembling a C file and a SPARC assembly file (respectively) and linking them. I'm working in a Unix environment. Here is the makefile: proj09.exe: proj09.driver.o proj09.support.o <tab>gcc -Wall proj09.driver.o proj09.support.o -o proj09.exe proj09.driver.o: proj09.driver.c /user/cse320/Projects/project09.support.h <tab>gcc -Wall -c proj09.driver.c /user/cse320/Projects/project09.support.h proj09.support.o: proj09.support.s <tab>gcc -Wall proj09.support.s When I try to make it, though, I get a

I know that when you read %r0 in SPARC CPU (and MIPS), always return 0, but I like to know Why ? What design decision is behind this and why ? It's just the way the CPU was designed. Ensuring that r0 is always set to zero is, for one thing, a way to avoid potentially costly memory accesses for a very common value. On one hand (reading), it's handy to have a register set aside to contain the value of zero so that you can use it. Otherwise, you would have to load zero into a register yourself. Many RISC processors tend to favour data manipulation in registers, accessing memory only for load and

Using crosstool scripts i've built under Cygwin the following compilers gcc-4.1.1 and 4.2.0 20061024 (prerelease) for Sparc architecture: $ ./sparc-unknown-linux-gnu-gcc -v Using built-in specs.
