Re: bitpos expansion patches summary


Hi Siddhesh,

another part of the review.


Thanks,
Jan

SEPARATE(Ensure that the value fits into CORE_ADDR): (eval.c:2075):	FUNC(value_from_pointer):	(LONGEST to CORE_ADDR)	[value_as_long(arg1) + mem_offset]
 - I do not understand this, you have correctly made 'long->LONGEST mem_offset;', I find it enough.
SAFE: (findcmd.c:184):	CMP:	(size_t to LONGEST)	[(val_bytes) > (sizeof(int64_t))]
 - (new entry) I miss here findcmd.c:190 fix, xrealloc 
   ULONGEST pattern_buf_size;
   pattern_buf = xrealloc (pattern_buf, pattern_buf_size);
   That second xrealloc parameter may overflow, there should be ENSURED_SIZET.
ENSURED_SIZET: (findcmd.c:218):	FUNC(memcpy):	(LONGEST to size_t)	[val_bytes]
 - Not needed, there is already called 'value_contents (v)'.

 - I agree unrelated but when found it should be fixed in a separate patch.
FIXED(Expand i): (f-valprint.c:178):	CMP:	(LONGEST to int)	[i < (f77_array_offset_tbl[nss][1])]
FIXED(Expand i): (f-valprint.c:189):	CMP:	(LONGEST to int)	[i < (f77_array_offset_tbl[nss][1])]

SAFE: (gdbtypes.c:3718):	ASSIGN:	(LONGEST to int)	[ left = (((f[0]).loc.bitpos) + 0) % alignment]
FIXED(Expand embedded_offset): (go-valprint.c:107):	FUNC(print_go_string):	(LONGEST to int)	[embedded_offset]
 - But print_go_string does not have embedded_offset expanded - failure of splint re-run.
UNSAFE_ALLOCA: (h8300-tdep.c:675):	FUNC(C_alloca):	(LONGEST to size_t)	[padded_len]
 - There should be alloca fix again with xmalloc and cleanup.
ENSURED_SIZET: (h8300-tdep.c:677):	FUNC(memset):	(LONGEST to size_t)	[padded_len]
 - This is redundant, there is already above it:
   char *contents = (char *) value_contents (args[argument]);
ENSURED_SIZET: (h8300-tdep.c:679):	FUNC(memcpy):	(LONGEST to size_t)	[len]
ENSURED_SIZET: (h8300-tdep.c:689):	FUNC(write_memory):	(LONGEST to ssize_t)	[padded_len]
ENSURED_SIZET: (h8300-tdep.c:716):	FUNC(write_memory):	(LONGEST to ssize_t)	[padded_len]
FIXED(Expand len): (h8300-tdep.c:747):	VARINIT(len):	(ULONGEST to int)	[(type)->length]
FIXED(Likewise): (h8300-tdep.c:784):	VARINIT(len):	(ULONGEST to int)	[(type)->length]
FIXED(Likewise): (h8300-tdep.c:851):	VARINIT(len):	(ULONGEST to int)	[(type)->length]
FIXED(Likewise): (h8300-tdep.c:881):	VARINIT(len):	(ULONGEST to int)	[(type)->length]
ENSURED_SIZET: (h8300-tdep.c:928):	FUNC(read_memory):	(ULONGEST to ssize_t)	[(type)->length]
 - Redundant, caller must have provided large enough READBUF.
