Note the thread_local10.C test fails on the 4.8 branch.
The problem is that the 4.8 branch doesn't contain the
https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/testsuite/g%2B%2B.dg/plugin/plugin.exp?r1=208416r2=208415pathrev=208416limit_changes=0view=patch
the change and thus if plugin.exp is run before tls.exp, the default flags
include -ansi.
Jason, do you think that change (just the plugin.exp one) is ok for 4.8.4, or
alternatively we can add something like
// { dg-options }
to the test.

[Bug target/64299] New: [SH] improve FPSCR.PR mode switching by reordering insns
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64299
Bug ID: 64299
Summary: [SH] improve FPSCR.PR mode switching by reordering
insns
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: olegendo at gcc dot gnu.org
Target: sh*-*-*
Compiling the following function with -O2 results in 4 FPSCR.PR mode switches:
double test_0 (const float* a, const float* b, const double* c, float x)
{
float aa = a[0] * b[0]; // single
double cc = c[0] + c[1]; // double
aa += b[1] * b[2]; // single
cc += c[2] + c[3]; // double
aa += b[3] * b[4]; // single
return aa / cc; // double
}
Since the calculations are independent and FPSCR flags are not read between the
operations, the fp insns can be reordered to reduce the amount of mode
switches. The resulting code should be the same as when doing the reordering
manually:
double test_1 (const float* a, const float* b, const double* c, float x)
{
float aa = a[0] * b[0] + b[1] * b[2] + b[3] * b[4]; // single
double cc = c[0] + c[1] + c[2] + c[3]; // double
return aa / cc; // double
}
which results in only 2 FPSCR.PR mode switches.
Moreover, the following example
double test_2 (const float* x, const double* y, unsigned int c)
{
float var0 = 0;
double var1 = 0;
while (c--)
{
float xx = x[0] * x[1] + x[2] + 123.0f;
x += 3;
double yy = y[0] + y[1];
y += 2;
var0 += xx;
var1 += yy;
}
return var0 + var1;
}
is a good candidate for doing loop distribution. Since var0 and var1 are
independent the loop can be replaced with a single precision loop and a double
precision loop, eliminating the FPSCR.PR mode switches inside the loop.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64294 Sebastian Andrzej Siewior gcc at breakpoint dot cc changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|INVALID |--- --- Comment #5 from Sebastian Andrzej Siewior gcc at breakpoint dot cc --- I re-open it. This time I attached the whole .i twice: - macro contains the second CLI_ISCONTAINED() invocation as a macro - static contains the second CLI_ISCONTAINED() as a static function The first one (macro) segfaults, the second one (static) works as a expected. The only obvious change I made in the static version is that the size argument is not signed but unsigned. Changing the type of sb_size to signed int results in the segfault again. I saw this problem with gcc-4.8 and 4.9. gcc 4.7 seems not to miss compile it. Comparing the disassemble between those two .i I see: - macro + static label: - 8b 44 24 44 mov0x44(%esp),%eax - 89 c1 mov%eax,%ecx + 8b 44 24 20 mov0x20(%esp),%eax + 85 c0 test %eax,%eax + 0f 84 8c fb ff ff je 3f0 petite_inflate2x_1to9+0x3f0 + 8b 4c 24 58 mov0x58(%esp),%ecx + 8b 44 24 20 mov0x20(%esp),%eax For me as a no-compiler guy it looks like the zero check has been removed because for some reason the size argument has to be != 0. I'm not sure if this is related but #26763 fixed a problem with the same macro. Sebastian
