Stock JikesRVM crashes at boot time

[qinsoon]

I was using FastAdaptiveImmix with stock JikesRVM (from https://github.com/JikesRVM/JikesRVM) and simply running rvm without any workload. Roughly half of the runs failed with one of the following issues.

• boot image mmap overwrites the JikesRVM executable mapping #160
• ASLR and "malloc returned something that is in RVM address space" #158
• Fatal error: glibc detected an invalid stdio handle #167
• Failing instruction starting at xxxx wasn't in RVM address space. Similar to Failing instruction starting at xxxxx wasn't in RVM address space #108.
• Appears to be stuck with no print and no return.

We can modify the addresses in build/targets/x86_64_m32-linux.properties to work around the issues. I tried the following settings and did not see any issue.

target.bootimage.code.address=0x84000000
target.bootimage.data.address=0x80000000
target.bootimage.rmap.address=0x87000000
target.max-mappable.address=0xd0000000

However, if we do this, we need to update VM space in mmtk-jikesrvm to be consistent, and set the vm layout for mmtk-core so it does not overlap.

The binding declares VM space addresses:

mmtk-jikesrvm/mmtk/src/api.rs

Lines 63 to 68 in 410d17f

	// set vm space
	builder
	.options
	.vm_space_start
	.set(unsafe { Address::from_usize(0x6000_0000) });
	builder.options.vm_space_size.set(0x800_0000);

mmtk-core heap range (VM space should not overlap with it):
