[Bug bootstrap/48000] [4.6 Regression] LTO bootstrap failed with bootstrap-profiled
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48000 --- Comment #4 from Zdenek Dvorak 2011-03-06 10:43:41 UTC --- Created attachment 23559 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23559 A proposed patch This fixes the problem uncovered by the previous fix. In fix_bb_placements, we restrict the placement changes to the basic blocks that originally were in the base loop (the loop containing the FROM basic block). This is achieved by marking the header of the loop visited, so that we never enter it to the processing queue. However, if FROM itself is the header of the loop, this fails, as we enter FROM to the queue unconditionally. Fixed by ending immediatelly if FROM is a loop header.

The test file used.
Working on M4RI, I found that changing a typedef from unsigned long long to
unsigned long caused one of the bench marks to become 50% slower. This is
peculiar since I'm on a 64-bit box where the size of both is 8 byte.
After investigation I ended up with the following function that is the cause
for at least 25% slow down, so a good case to investigate this (compiler) bug
(assuming you're willing to call not-optimal compiled code a bug).
===Start of File=
#define RADIX 64
typedef unsigned long word;
typedef unsigned long size_t;
typedef struct _mm_block {
size_t size;
void *data;
} mmb_t;
typedef struct {
mmb_t *blocks;
size_t nrows;
size_t ncols;
size_t width;
size_t offset;
word** rows;
} mzd_t;
typedef unsigned char BIT;
#define ONE ((word)1)
#define GET_BIT(w, spot) (((w) >> (RADIX - 1 - (spot))) & ONE)
static inline BIT mzd_read_bit(const mzd_t *M, const size_t row, const size_t
col ) {
return GET_BIT(M->rows[row][(col+M->offset)/RADIX], (col+M->offset) % RADIX);
}
void foo(mzd_t* DST, mzd_t const* A, int i, int eol)
{
#ifdef OLDCODE
unsigned long long* temp = (unsigned long long*)DST->rows[i];
for (int j = 0; j < eol; j += RADIX, ++temp)
for (int k = RADIX - 1; k >= 0; --k)
*temp |= ((unsigned long long)mzd_read_bit(A, j+k,
i+A->offset))<<(RADIX-1-k);
#else
word* temp = DST->rows[i];
for (int j = 0; j < eol; j += RADIX, ++temp)
for (int k = RADIX - 1; k >= 0; --k)
*temp |= ((word)mzd_read_bit(A, j+k, i+A->offset))<<(RADIX-1-k);
#endif
}
===END OF FILE
Compile this with on a x86_64 machine with:
gcc -std=gnu99 -O2 -c transposebody.c -fPIC -DPIC -o transposebody.o -DOLDCODE
-save-temps
one with and without the -DOLDCODE will show a remarkable difference in the
resulting assembly code, using more registers and a lot more instructions when
OLDCODE is not defined.
Note that the only difference is that with OLDCODE defined we cast the unsigned
char returned from mzd_read_bit to an unsigned long long instead of to an
unsigned long, and the type of temp is unsigned long long* instead of unsigned
long*.

[Bug bootstrap/47907] Bootstrap failure: libiberty/hashtab.c: error: conflicting types for 'int_fast16_t'
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47907
--- Comment #2 from Daniel Richard G. 2011-03-06
22:28:42 UTC ---
I've managed to work around this issue with the following steps:
1. Create a site configuration file with the following:
ac_cv_header_stdint_h=no
gcc_cv_header_stdint_h=no
glibcxx_cv_c99_stdint_tr1=no
gt_cv_header_stdint_h=no
jm_ac_cv_header_stdint_h=no
2. Set the environment variable CONFIG_SITE to the path to this file.
3. /path/to/gcc-4.5.2/configure --yadda --yadda --whatever
4. Edit the top-level Makefile to replace all lines of the form
CONFIG_SITE=no-such-file $(SHELL) $${libsrcdir}/configure \
with e.g.
XXX_CONFIG_SITE=no-such-file $(SHELL) $${libsrcdir}/configure \
(That is, so CONFIG_SITE is not overridden at any point.)
5. Bootstrap GCC.
The problem appears to be that GCC's stdint.h (which in this case is really
gcc-4.5.2/gcc/ginclude/stdint-gcc.h, because the system has no stdint.h of its
own) is incompatible with the system's inttypes.h. Blacklisting inttypes.h
doesn't work, because the system's sys/types.h #includes it. Blacklisting GCC's
stdint.h, however, allows the bootstrap to complete (modulo bug #48009).

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48009 --- Comment #1 from Daniel Richard G. 2011-03-06 22:33:42 UTC --- Editing the strtof() prototype in $top_builddir/gcc/include-fixed/stdlib.h allows the bootstrap to complete successfully. Looks like all this needs is a tweak to fixincludes.
