From 165cd47f5eabd61fc53c930450493378ac9f1a8c Mon Sep 17 00:00:00 2001 From: Michael Snyder Date: Fri, 17 Nov 2000 01:30:53 +0000 Subject: 2000-11-16 Michael Snyder * regcache.c (read_register_bytes): Failing to set register_valid is not necessarily an error, if the register is a pseudo-register. Some pseudo-registers are never marked as valid, so that they will be read anew every time. Determining if a pseudo-register is valid (or should be marked invalid) may be difficult, whereas just recomputing it may be cheap. --- gdb/regcache.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'gdb/regcache.c') diff --git a/gdb/regcache.c b/gdb/regcache.c index 2326b34..104bff7 100644 --- a/gdb/regcache.c +++ b/gdb/regcache.c @@ -391,7 +391,14 @@ read_register_bytes (int inregbyte, char *myaddr, int inlen) FETCH_PSEUDO_REGISTER (regno); if (!register_valid[regno]) - error ("read_register_bytes: Couldn't update register %d.", regno); + { + /* Sometimes pseudoregs are never marked valid, so that they + will be fetched every time (it can be complicated to know + if a pseudoreg is valid, while "fetching" them can be cheap). + */ + if (regno < NUM_REGS) + error ("read_register_bytes: Couldn't update register %d.", regno); + } } if (myaddr != NULL) -- cgit v1.1
