Assembly file
Attached is an assembly file demonstrating the problem. It's derived
from the assembly output at -O1 for the gcc.c-torture/execute/packed-aligned.c
test.
I changed this code
addil LR'g_expect-$global$,%r27
fstd %fr22,RR'g_expect-$global$(%r1)
in main to
addil LR'g_expect-$global$,%r27
fstd %fr22,RR'g_expect-$global$(%r1)
ldo RR'g_expect-$global$(%r1),%r1
fstd %fr22,0(%r1)
so I could see what was happening to the symbolic relocation in the fstd
instruction.
This is the code in the final executable:
10574: 2b 60 00 00 addil L%0,dp,r1
10578: 70 36 00 20 std r22,10(r1)
1057c: 34 21 00 20 ldo 10(r1),r1
10580: 2c 20 12 16 fstd fr22,0(r1)
The fstd instruction has changed to a std instruction.
In the .o object file, we have:
7c: 2b 60 00 00 addil L%0,dp,r1
80: 70 36 00 02 fstd fr22,0(r1)
84: 34 21 00 00 ldo 0(r1),r1
88: 2c 20 12 16 fstd fr22,0(r1)
We have the following relocations:
0000007c R_PARISC_DPREL21L g_expect
00000080 R_PARISC_DPREL14R g_expect
00000084 R_PARISC_DPREL14R g_expect
The format 3 (im10a) variants of ldd and fldd differ in bit 30. ldd has a
0 and fldd a 1.
