## Release Notes

The release notes are generated from `src/docs/release/notes.md`.

### Schema

Every `h2` tag and `h3` will be listed in the generated TOC.

After every `h3` all content after the first element (usually a `p`) will be collapsed/expandable, up until the next `h3`, or `h2`.

After every `h4` all content will be collapsed/expandable, up until the next `h4`, `h3` or `h2`.

	C_LACON    /* $n(REG) where n <= int32 */
	C_DACON    /* $n(REG) where n <= int64 */
	C_BRA      /* A short offset argument to a branching instruction */
	C_BRAPIC   /* Like C_BRA, but requires an extra NOP for potential TOC restore by the linker. */
	C_ZOREG    /* An $0+reg memory op */
	C_SOREG    /* An $n+reg memory arg where n is a 16 bit signed offset */
	C_LOREG    /* An $n+reg memory arg where n is a 32 bit signed offset */

1. Special register usage in Go asm

The following registers should not be modified by user Go assembler code.

	R0: Go code expects this register to contain the value 0.
	R1: Stack pointer
	R2: TOC pointer when compiled with -shared or -dynlink (a.k.a position independent code)
	R13: TLS pointer
	R30: g (goroutine)

Register names:

	Rn is used for general purpose registers. (0-31)

	p("JMP (R30)")

	// Add integer registers R3-R29
	// R0 (zero), R1 (SP), R30 (g) are special and not saved here.
	// R2 (TOC pointer in PIC mode), R12 (function entry address in PIC mode) have been saved in sigctxt.pushCall.
	// R31 (REGTMP) will be saved manually.
	var l = layout{sp: "R1", stack: 32 + 8} // MinFrameSize on PPC64, plus one word for saving R31

	// called from a larger pthread or sigaltstack stack. Can the checker be improved to not
	// flag a direct call here?
	MOVD	$runtime·sigtrampgo<ABIInternal>(SB), R12
	MOVD	R12, CTR
	BL	(CTR)
	// Restore R2 (TOC pointer) in the event it might be used later in this function.
	// If this was not compiled as shared code, R2 is undefined, reloading it is harmless.
