[Bug c++/22190] New: Bad registers optimization
I add below a ~100-line code. When compiling the code with
g++ -march=pentium4 -O3 -g -S allocator.cc
(g++ is version 3.4.2)
I get this assembly code:
.loc 1 50 0
jne .L2
.loc 1 93 0
movl4(%ecx), %ebx // ebx now holds page-prev
movl(%ecx), %eax// eax now holds page-next
.loc 1 97 0
movl_ZN8PagePool9free_listE, %edx // edx now holds free_list
.loc 1 93 0
movl%eax, (%ebx)// page-prev-next = page-next
.loc 1 97 0
movl%edx, (%ecx)// page-next = free_list-next
.loc 1 98 0
movl%ecx, _ZN8PagePool9free_listE // free_list-next = page
.loc 1 94 0
movl(%ecx), %esi// esi now holds page-next
// (BUG: This is actually free_list-next)
movl%ebx, 4(%esi) // page-next-prev =
page-prev
// (BUG: this is actually
// page-next-prev = free_list-next)
The optimization that moved the assembly of line 97 to be before line 94 causes
incorrect value into 4(%esi) (= page-next-prev)
The C++ code:
uncommneting the printf fixes this problem since apparently it prevent this
optimization from taking place

--- Additional Comments From steven at gcc dot gnu dot org 2005-06-26 12:26 --- Taking three or more registers as in the test cases from comment #5 and from Bug 21469, or using regparam, is just asking for trouble on a target with only six registers available, total. While this is a regression, we also have cases that didn't compile with old compilers and now do. It is just a matter of luck if you're going to fix registers -- even the order in which the statements are expanded to RTL can matter for the register pressure, and in this case y'all are so unlucky to need a larger number of registers than what you've left available to the compiler. I believe this bug should be closed as SUSPEND unless test cases exist that use neither regparam nor global register variables. -- What|Removed |Added Status|NEW |WAITING http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16185
[Bug libgcj/22189] Table Full in gcj-dbtool if -m option used with smallest possible input
--- Additional Comments From greenrd at greenrd dot org 2005-06-26 12:39 --- The problem is that a PersistentByteMap of capacity 1 is created by -m, but when a PersistentByteMap is created with capacity 1, its capacity method incorrectly returns 0. This is because, when it is created, confusingly, the capacity field is set to (int) (capacity*3/2),which in this case is 1, and the capacity() method then returns (int) (the capacity field * 2 / 3), which is (int) (2 * 1 / 3) = 0. The first thing I would do is, we have 3 things (initial capacity, capacity field, capacity method), all with the same name, but not meaning the same thing, so I would do some renames to avoid confusion. Then I would fix the actual bug.

--- Additional Comments From schlie at comcast dot net 2005-06-26 15:06 --- (In reply to comment #7) (In reply to comment #6) The problem here is that gcc is using a DImode register to handle 6 byte (int+long) structure. Why I have no idea! This is so it does not store it on the stack. As I said in comment #5, this is a target issue and have nothing to do with DImode. It would seem more desireable given the intended purpose to avoid pushing it on the stack so that it's elements may be more effeciencly accessed, that it's coresponding elements be allocated within the register file (as opposed to the whole struct remaining packed into an alllocated DI mode integer), so that it's elements may be effeciently accessed without needing to rip them out or reassemble them into the otherwise packed monolithic structure? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11180

What|Removed |Added
GCC target triplet|hppa-*-linux, hppa2.0w-hp- |hppa*-*-{linux,hpux}
|hpux11.11 |
This problem doesn't affect hppa64 as it doesn't require function
pointer canonicalization.
