Subject: pahole regression: -a no longer works?
Date: Thu, 25 Jun 2009 21:29:28 -0400 [thread overview]
Message-ID: <db65a1cd0906251829p5e10b56fo861728d35ea54fb0@mail.gmail.com> (raw)
I've just noticed that pahole's -a flag does not seem to result in
typedef'd structs being printed anymore.
For example, with Debian's dwarves 1.3-1, on a self-compiled libVEX
from valgrind, I see loads of typedef'd struct types like this one:
typedef struct {
IRTypeEnv * type_env; /* 0 4 */
HReg * vregmap; /* 4 4 */
Int n_vregmap; /* 8 4 */
HInstrArray * code; /* 12 4 */
Int vreg_ctr; /* 16 4 */
/* size: 20, cachelines: 1 */
/* last cacheline: 20 bytes */
} ISelEnv; /* definitions: 1 */
but in the latest, I get only the following three:
struct _IRConst {
IRConstTag tag; /* 0 4 */
union {
Bool U1; /* 1 */
UChar U8; /* 1 */
UShort U16; /* 2 */
UInt U32; /* 4 */
ULong U64; /* 8 */
Double F64; /* 8 */
ULong F64i; /* 8 */
UShort V128; /* 2 */
} Ico; /* 4 8 */
/* size: 12, cachelines: 1, members: 2 */
/* last cacheline: 12 bytes */
};
struct _IRExpr {
IRExprTag tag; /* 0 4 */
union {
struct {
Int binder; /* 4 4 */
} Binder; /* 4 */
struct {
Int offset; /* 4 4 */
IRType ty; /* 8 4 */
} Get; /* 8 */
struct {
IRRegArray * descr; /* 4 4 */
IRExpr * ix; /* 8 4 */
Int bias; /* 12 4 */
} GetI; /* 12 */
struct {
IRTemp tmp; /* 4 4 */
} RdTmp; /* 4 */
struct {
IROp op; /* 4 4 */
IRExpr * arg1; /* 8 4 */
IRExpr * arg2; /* 12 4 */
IRExpr * arg3; /* 16 4 */
IRExpr * arg4; /* 20 4 */
} Qop; /* 20 */
struct {
IROp op; /* 4 4 */
IRExpr * arg1; /* 8 4 */
IRExpr * arg2; /* 12 4 */
IRExpr * arg3; /* 16 4 */
} Triop; /* 16 */
struct {
IROp op; /* 4 4 */
IRExpr * arg1; /* 8 4 */
IRExpr * arg2; /* 12 4 */
} Binop; /* 12 */
struct {
IROp op; /* 4 4 */
IRExpr * arg; /* 8 4 */
} Unop; /* 8 */
struct {
IREndness end; /* 4 4 */
IRType ty; /* 8 4 */
IRExpr * addr; /* 12 4 */
} Load; /* 12 */
struct {
IRConst * con; /* 4 4 */
} Const; /* 4 */
struct {
IRCallee * cee; /* 4 4 */
IRType retty; /* 8 4 */
IRExpr * * args; /* 12 4 */
} CCall; /* 12 */
struct {
IRExpr * cond; /* 4 4 */
IRExpr * expr0; /* 8 4 */
IRExpr * exprX; /* 12 4 */
} Mux0X; /* 12 */
} Iex; /* 4 20 */
/* size: 24, cachelines: 1, members: 2 */
/* last cacheline: 24 bytes */
};
struct _IRStmt {
IRStmtTag tag; /* 0 4 */
union {
struct {
} NoOp; /* 0 */
struct {
Addr64 addr; /* 4 8 */
Int len; /* 12 4 */
} IMark; /* 12 */
struct {
IRExpr * base; /* 4 4 */
Int len; /* 8 4 */
IRExpr * nia; /* 12 4 */
} AbiHint; /* 12 */
struct {
Int offset; /* 4 4 */
IRExpr * data; /* 8 4 */
} Put; /* 8 */
struct {
IRRegArray * descr; /* 4 4 */
IRExpr * ix; /* 8 4 */
Int bias; /* 12 4 */
IRExpr * data; /* 16 4 */
} PutI; /* 16 */
struct {
IRTemp tmp; /* 4 4 */
IRExpr * data; /* 8 4 */
} WrTmp; /* 8 */
struct {
IREndness end; /* 4 4 */
IRExpr * addr; /* 8 4 */
IRExpr * data; /* 12 4 */
} Store; /* 12 */
struct {
IRDirty * details; /* 4 4 */
} Dirty; /* 4 */
IRExpr * data; /* 8 4 */
} WrTmp; /* 8 */
struct {
IREndness end; /* 4 4 */
IRExpr * addr; /* 8 4 */
IRExpr * data; /* 12 4 */
} Store; /* 12 */
struct {
IRDirty * details; /* 4 4 */
} Dirty; /* 4 */
struct {
IRMBusEvent event; /* 4 4 */
} MBE; /* 4 */
struct {
IRExpr * guard; /* 4 4 */
IRJumpKind jk; /* 8 4 */
IRConst * dst; /* 12 4 */
} Exit; /* 12 */
} Ist; /* 4 16 */
/* size: 20, cachelines: 1, members: 2 */
/* last cacheline: 20 bytes */
};
This should be pretty easy to reproduce, but if not I could provide
you with an .o file... I'd bisect it myself if it weren't for the fact
that libebl.a is no longer available on Debian squeeze/sid, which
means I can't build without patching the cmake :-(
