+/**
+ * This function fixes up addresses that are used to match PCs for
+ * hooking simulator events on to target function executions.
+ *
+ * Alpha binaries may have multiple global offset table (GOT)
+ * sections. A function that uses the GOT starts with a
+ * two-instruction prolog which sets the global pointer (gp == r29) to
+ * the appropriate GOT section. The proper gp value is calculated
+ * based on the function address, which must be passed by the caller
+ * in the procedure value register (pv aka t12 == r27). This sequence
+ * looks like the following:
+ *
+ * opcode Ra Rb offset
+ * ldah gp,X(pv) 09 29 27 X
+ * lda gp,Y(gp) 08 29 29 Y
+ *
+ * for some constant offsets X and Y. The catch is that the linker
+ * (or maybe even the compiler, I'm not sure) may recognize that the
+ * caller and callee are using the same GOT section, making this
+ * prolog redundant, and modify the call target to skip these
+ * instructions. If we check for execution of the first instruction
+ * of a function (the one the symbol points to) to detect when to skip
+ * it, we'll miss all these modified calls. It might work to
+ * unconditionally check for the third instruction, but not all
+ * functions have this prolog, and there's some chance that those
+ * first two instructions could have undesired consequences. So we do
+ * the Right Thing and pattern-match the first two instructions of the
+ * function to decide where to patch.
+ *
+ * Eventually this code should be moved into an ISA-specific file.

- * This function fixes up addresses that are used to match PCs for
- * hooking simulator events on to target function executions.
- *
- * Alpha binaries may have multiple global offset table (GOT)
- * sections. A function that uses the GOT starts with a
- * two-instruction prolog which sets the global pointer (gp == r29) to
- * the appropriate GOT section. The proper gp value is calculated
- * based on the function address, which must be passed by the caller
- * in the procedure value register (pv aka t12 == r27). This sequence
- * looks like the following:
- *
- * opcode Ra Rb offset
- * ldah gp,X(pv) 09 29 27 X
- * lda gp,Y(gp) 08 29 29 Y
- *
- * for some constant offsets X and Y. The catch is that the linker
- * (or maybe even the compiler, I'm not sure) may recognize that the
- * caller and callee are using the same GOT section, making this
- * prolog redundant, and modify the call target to skip these
- * instructions. If we check for execution of the first instruction
- * of a function (the one the symbol points to) to detect when to skip
- * it, we'll miss all these modified calls. It might work to
- * unconditionally check for the third instruction, but not all
- * functions have this prolog, and there's some chance that those
- * first two instructions could have undesired consequences. So we do
- * the Right Thing and pattern-match the first two instructions of the
- * function to decide where to patch.
- *
- * Eventually this code should be moved into an ISA-specific file.
