From 36b11add17bf287b541a107ee64f7e313e77092f Mon Sep 17 00:00:00 2001 From: Jan Kratochvil Date: Sun, 9 Oct 2011 19:41:17 +0000 Subject: gdb/ Support @entry in input expressions. * c-exp.y (ENTRY, unknown_cpp_name): New. (exp: UNKNOWN_CPP_NAME): Change to `exp: unknown_cpp_name'. (unknown_cpp_name: UNKNOWN_CPP_NAME, unknown_cpp_name: ENTRY) (variable: name_not_typename '@' ENTRY, name: ENTRY) (name_not_typename: ENTRY): New. (yylex): Recognize ENTRY. * eval.c (evaluate_subexp_standard): Support also OP_VAR_ENTRY_VALUE. * expprint.c (print_subexp_standard, dump_subexp_body_standard): Likewise. * parse.c (operator_length_standard): Likewise. * std-operator.def: New operator OP_VAR_ENTRY_VALUE. gdb/doc/ Support @entry in input expressions. * gdb.texinfo (Variables): Describe @entry names suffix. (Print Settings): Add anchor for `set print entry-values'. gdb/testsuite/ Support @entry in input expressions. * gdb.arch/amd64-entry-value.exp (entry: p i@entry, entry: p j@entry) (entry_stack: p s1@entry, entry_stack: p s2@entry) (entry_stack: p d9@entry, entry_stack: p da@entry, tailcall: p i@entry) (tailcall: p j@entry): New tests. * gdb.cp/koenig.cc (A::entry): New function. (main): Call it. * gdb.cp/koenig.exp (p entry (c)): New test. --- gdb/expprint.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'gdb/expprint.c') diff --git a/gdb/expprint.c b/gdb/expprint.c index 2b6e416..0e0f1c3 100644 --- a/gdb/expprint.c +++ b/gdb/expprint.c @@ -135,6 +135,16 @@ print_subexp_standard (struct expression *exp, int *pos, } return; + case OP_VAR_ENTRY_VALUE: + { + struct block *b; + + (*pos) += 2; + fprintf_filtered (stream, "%s@entry", + SYMBOL_PRINT_NAME (exp->elts[pc + 1].symbol)); + } + return; + case OP_LAST: (*pos) += 2; fprintf_filtered (stream, "$%d", @@ -853,6 +863,13 @@ dump_subexp_body_standard (struct expression *exp, SYMBOL_PRINT_NAME (exp->elts[elt + 1].symbol)); elt += 3; break; + case OP_VAR_ENTRY_VALUE: + fprintf_filtered (stream, "Entry value of symbol @"); + gdb_print_host_address (exp->elts[elt].symbol, stream); + fprintf_filtered (stream, " (%s)", + SYMBOL_PRINT_NAME (exp->elts[elt].symbol)); + elt += 2; + break; case OP_LAST: fprintf_filtered (stream, "History element %ld", (long) exp->elts[elt].longconst); -- cgit v1.1
