SPARC(Scalable Processor Architecture) Sun Microsystems's specific CPU.

SPARC is a RISC instruction set architecture (ISA) developed by Sun Microsystems (now merged into Oracle), introduced in mid-1987.

SPARC hardware often runs Solaris, the Unix operating system, but other OSes run on SPARC hardware, and runs on more than just SPARC hardware.

SPARC doesn't allow unaligned loads, so SIGBUS (bus error) faults are a common problem when porting C or C++ to SPARC from x86 (for example).

In assembly, SPARC's 32 architectural registers are a sliding window onto a virtual register file. The save instruction that slides the window might or might not spill to memory, depending on whether the CPU microarchitecture is out of registers when it runs.

nanoseconds to milliseconds - fast division by 1000000

I'm wanting to convert the output from gethrtime to milliseconds. The obvious way to do this is to divide by 1000000. However, I'm doing this quite often and wonder if it could become a bottleneck. Is there an optimized divide operation when dealing…

Handling of integer with values > 2^32 on Sparc 32 bits

I coded a little program that measures the time spent into a loop (via an inline Sparc assembly code snippet). Everything is right until I set number of iterations above roughly 4.0+9 (above 2^32). Here's the code snippet : #include…

Run Sparc binaries without Sparc hardware

I've been curious in the past few months in trying my hand at doing some assembly for the SPARC processor (either V8 or V9). My question is this, I have no access to a SPARC machine, is there a way I can run SPARC binaries on my x86 machine? I've…

Disassembled gcc output appears to do a "call 0" instead of "call function-offset", but works correctly

I had just a look at a very simple SPARC assembly output that I got from this C programm: int addition_func(int a, int b) { return(a+b); } void main() { int a = 20; int b = 19; int res; res = addition_func(a, b); } Disassembly of section…

Unable to cross-compile to SPARC using clang

So here's the situation: I need to be able to compile binaries from a Linux machine (on Ubuntu, for what it's worth) which are able to run from a SPARC server. The program I'm trying to compile is very simple: #include #include…

C++ IDE for Solaris SPARC

We've been given a C++ code base that was apparently developed using Rational Apex as the front end. In our opinion, Apex is less than ideal for C++ development. We're looking for an IDE we can use that has syntax highlighting, code-walking (go to…

GCC inline assembly for SPARC: How to handle integer doubleword pairs?

From what I understand, in SPARC, 32-bit integer quantities are stored in single registers and 64-bit integer quantities are stored in adjacent register pairs, with the even register containing the high 32 bits and the odd register containing the…

When a out-of-order processor encounters something like LOAD R1, 0x1337 LOAD R2, $R1 LOAD R3, 0x42 Assuming that all accesses will result in a cache miss, can the processor ask the memory controller for the contents of 0x42 before the it asks for…
