2010-10-206l: correct logic for morestack choiceRuss Cox
The frame that gets allocated is for both the args and the autos. If together they exceed the default frame size, we need to tell morestack about both so that it allocates a large enough frame. Sanity check stack pointer in morestack to catch similar bugs. R=ken2 CC=golang-dev https://golang.org/cl/2609041

2010-10-195l, 6l, 8l: link pclntab and symtab as ordinary rodata symbolsRuss Cox
That is, move the pc/ln table and the symbol table into the read-only data segment. This eliminates the need for a special load command to map the symbol table into memory, which makes the information available on systems that couldn't handle the magic load to 0x99000000, like NaCl and ARM QEMU and Linux without config_highmem=y. It also eliminates an #ifdef and some clumsy code to find the symbol table on Windows. The bad news is that the binary appears to be bigger than it used to be. This is not actually the case, though: the same amount of data is being mapped into memory as before, and the tables are still read-only, so they're still shared across multiple instances of the binary as they were before. The difference is just that the tables aren't squirreled away in some section that "size" doesn't know to look at. This is a checkpoint. It probably breaks Windows and breaks NaCl more than it used to be broken, but those will be fixed. The logic involving -s needs to be revisited too. Fixes #871.

2010-10-188l, runtime: initial support for Plan 9Yuval Pavel Zholkover
No multiple processes/locks, managed to compile and run a hello.go (with print not fmt). Also test/sieve.go seems to run until 439 and stops with a 'throw: all goroutines are asleep - deadlock!' - just like runtime/tiny. based on Russ's suggestions at: http://groups.google.com/group/comp.os.plan9/browse_thread/thread/cfda8b82535d2d68/243777a597ec1612 Build instructions: cd src/pkg/runtime make clean && GOOS=plan9 make install this will build and install the runtime. When linking with 8l, you should pass -s to suppress symbol generation in the a.out, otherwise the generated executable will not run. This is runtime only, the porting of the toolchain has already been done: http://code.google.com/p/go-plan9/source/browse in the plan9-quanstro branch.

2010-10-175l: stop using R12 as SBRuss Cox
Because the SB is only good for 8k and Go programs tend to have much more data than that, SB doesn't save very much. A fmt.Printf-based hello world program has 360 kB text segment. Removing SB makes the text 500 bytes (0.14%) longer. R=ken2, r2, ken3 CC=golang-dev https://golang.org/cl/2487042

2010-10-156l: function at a time code layoutRuss Cox
Also change the span-dependent jump algorithm to use fewer iterations: * resolve forward jumps at their targets (comefrom list) * mark jumps as small or big and only do small->big * record whether a jump failed to be encodable These changes mean that a function with only small jumps can be laid out in a single iteration, and the vast majority of functions take just two iterations. I was seeing a maximum of 5 iterations before; the max now is 3 and there are fewer that get even that far. R=ken2 CC=golang-dev https://golang.org/cl/2537041
2010-10-156l, 8l: avoid recursion in asmandszRuss Cox
The old code said if(x) { handle a return } aa = *a rewrite aa to make x true recursivecall(&aa) The new code says params = copy out of a if(!x) { rewrite params to make x true } handle params but it's hard to see that in the Rietveld diffs because it gets confused by changes in indentation. Avoiding the recursion makes other changes easier. R=ken2 CC=golang-dev https://golang.org/cl/2533041
