GCC 4.3.0 Status Report (2008-01-02)

Status == We are in Stage 3. When we reach 100 open regressions, we will go to regression-only mode. When we approach the 4.3.0 release, we will create a branch, and open Stage 1 for 4.4.0. Quality Data We have approximately zero change in the quality data over the last month

plugin help: Inserting a function call in gimple code?

I'm experimenting with the gimple plugin infrastructure and I'm having trouble instrumenting code in a way that is compatible with the optimizer. Here's a simple example that is intended to insert the function call "__memcheck_register_argv(argc, argv)" at the beginning of main. The code runs

PATCH: PR gas/5534: "XXX PTR" isn't checked properly in Intel syntax

If an instruction is marked with IgnoreSize, we don't check for memory size in Intel mode. I am checking in this patch to create the infrastructure to handle it properly. I will fix movq first and work on others later. Eventually, the x86 assembler will check memory size for all instructions in Int

Restricted or no run time in Ada

Hi, I got a simple hello world style multiboot kernel working again recently and it has got me thinking about how I should be using GNAT. Basically, I built a cross compiler for binutils and gcc to target i386-elf (I will be wanting to play with other targets in the future, e.g. mips-elf, arm-elf

Does GIMPLE tree comprise ARRAY_REF/ARRAY_REF_RANGE node

Hi, I find that in the function expand_expr_real_1(), which translates the GIMPLE tree nodes to RTL. There are codes to process the ARRAY_REF/ARRAY_REF_RANGE node. I wrote a test program in C such like this, void f(int s1[], int s2[], int s3[]) { int j; for (j = 0; j < 16; j++) s3[j] = s1[j] + s2
