[LLVMdev] Boehm GC + static variables?
...he boehm gc doesn't already see the globals, since there's a reference to their memory from the JMM, but maybe it doesn't scan mmap regions by default.

[LLVMdev] Boehm GC + static variables?
I've implemented this by adding calls to GC_add_roots(<first global in module>,<last global in module>+1) to the llvm.global_ctors before any other static initialization code for the module. This should be safe assuming that: - global variables are laid out in memory in the order they appear in their module (and ideally contiguously with...

[LLVMdev] Boehm GC + static variables?
Hi, I'm running LLVM bitcode generated by my compiler under lli. The bitcode is linked against Boehm GC (lli -load=/usr/lib/libgc.so). It looks like Boehm GC isn't scanning global variables and as a result objects referenced only through globals are being prematurely collected. I understand that Boehm GC needs to see the data segment containing my global variables as a root. For native
