Address issues triggered by the MIPS ISA bit handling change, usually in
tests that make artificial DWARF-2 records:
* gdb.cp/expand-psymtabs-cxx.exp -- this test is debugging an object file
and assuming addresses will be 0; with the ISA bit set code addresses
are 1 instead:
(gdb) PASS: gdb.cp/expand-psymtabs-cxx.exp: set language c++
p 'method(long)'
$1 = {void (long)} 0x1 <method(long)>
(gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: before expand
p method
$2 = {void (long)} 0x1 <method(long)>
(gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: force expand
p 'method(long)'
$3 = {void (long)} 0x1 <method(long)>
(gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: after expand
Fix by matching any hex number, there's no value AFAICT for the test
in matching 0 exactly, and I suppose the method's offset within
section can be non-zero for some other reasons on other targets too.
* gdb.cp/nsalias.exp -- this assumes instructions can be aligned
arbitrarily and places code labels at odd addreses, setting the ISA
bit and wreaking havoc:
(gdb) PASS: gdb.cp/nsalias.exp: print outer::inner::innermost::x
list outer::inner::innermost::foo
Function "outer::inner::innermost::foo" not defined.
(gdb) FAIL: gdb.cp/nsalias.exp: list outer::inner::innermost::foo
break *outer::inner::innermost::foo
No symbol "foo" in namespace "outer::inner::innermost".
(gdb) FAIL: gdb.cp/nsalias.exp: setting breakpoint at
*outer::inner::innermost::foo
delete $bpnum
No breakpoint number 6.
(gdb) FAIL: gdb.cp/nsalias.exp: (outer::inner::innermost): delete $bpnum
-- etc., etc... Fix by aligning labels to 4; required by many
processors.
* gdb.dwarf2/dw2-canonicalize-type.exp, gdb.dwarf2/dw2-empty-pc-range.exp,
gdb.dwarf2/pr11465.exp -- these assume an instruction and consequently
a function can take as little as 1 byte, which makes it impossible to
look up a code symbol by an address with the ISA bit set as the
address is already beyond the end of the function:
(gdb) ptype f
No symbol "f" in current context.
(gdb) FAIL: gdb.dwarf2/dw2-canonicalize-type.exp: ptype f
(gdb) PASS: gdb.dwarf2/dw2-empty-pc-range.exp: empty range before CU load
ptype realrange
No symbol "realrange" in current context.
(gdb) FAIL: gdb.dwarf2/dw2-empty-pc-range.exp: valid range after CU load
(gdb) p N::c.C
Cannot take address of method C.
(gdb) FAIL: gdb.dwarf2/pr11465.exp: p N::c.C
-- fix by increasing the size of the function to 4 (perhaps code in
gdb/mips-tdep.c could look up code symbols up to twice, with and
failing that without the ISA bit set, but it seems wrong to me to
implement specific handling for invalid code just to satisfy test
cases that assume too much about the target).
* gdb.dwarf2/dw2-case-insensitive.exp -- an artificial code label is
created, but does not work because data (a `.align' pseudo-op in this
case) follows and as a result the label has no MIPS16 or microMIPS
annotation in the symbol table:
(gdb) PASS: gdb.dwarf2/dw2-case-insensitive.exp: set case-sensitive off
info functions fUnC_lang
All functions matching regular expression "fUnC_lang":
File file1.txt:
foo FUNC_lang(void);
Non-debugging symbols:
0x004006e0 FUNC_lang_start
(gdb) FAIL: gdb.dwarf2/dw2-case-insensitive.exp: regexp case-sensitive off
-- fix by adding a `.insn' pseudo-op on MIPS targets; the pseudo-op
marks data as instructions.
* gdb.dwarf2/dw2-stack-boundary.exp -- the test case enables complaints
and assumes none will be issued beyond ones explicitly arranged by the
test case, however overlapping sections are noticed while minimal
symbols are looked up by `mips_adjust_dwarf2_addr' in DWARF-2 record
processing:
(gdb) set complaints 100
(gdb) PASS: gdb.dwarf2/dw2-stack-boundary.exp: set complaints 100
file ./dw2-stack-boundary
Reading symbols from ./dw2-stack-boundary...location description stack
underflow...location description stack overflow...unexpected overlap
between:
(A) section `.reginfo' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x18)
(B) section `*COM*' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x0).
Will ignore section B...unexpected overlap between:
(A) section `.reginfo' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x18)
(B) section `*UND*' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x0).
Will ignore section B...unexpected overlap between:
(A) section `.reginfo' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x18)
(B) section `*ABS*' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x0).
Will ignore section B...done.
(gdb) FAIL: gdb.dwarf2/dw2-stack-boundary.exp: check partial symtab errors
-- fix by ignoring any extra noise as long as what we look for is
found.
* gdb.cp/expand-psymtabs-cxx.exp: Accept any address of
`method(long)', not just 0x0.
* gdb.cp/nsalias.exp: Align code labels to 4.
* gdb.dwarf2/dw2-canonicalize-type.S (main): Expand to 4-bytes.
* gdb.dwarf2/dw2-empty-pc-range.S (main): Likewise.
* gdb.dwarf2/pr11465.S (_ZN1N1cE): Likewise.
* gdb.dwarf2/dw2-case-insensitive.c (START_INSNS): New macro.
(cu_text_start, FUNC_lang_start): Use `START_INSNS'.
* gdb.dwarf2/dw2-stack-boundary.exp: Accept noise in complaints.
