Looks like you have done some experiments for splitting hug files ?
I can not find any patch, could you share much more idea with it ?

Hi，
I consider four ways to implementation it,
and maybe we can use ‘csplit’ tool to split output file, is that right ?

Hi,
Form My ABI, float register is used by function call,
I want to pack float a and b into double v without any memory load/store,
The flowing is my demo:
Typedef union {
float ff[2];
double v;
} double_u;
Double pack_float (float a, float b) {
double_u tmp;
t
insn seqs:
s1:
__builtin_set_float_convert_mode(0);
r1 = __builtin_load(a1, a2);
r2 = __builtin_float_convert(r1);
__builtin_store(a3, r2);
__builtin_set_float_convert_mode(0);
s2:
__builtin_set_float_convert_mode(1);
r1 = __builtin_load(a1
Hi,
Got it, Thanks :)

Hi,
Is there any API or common codes to check any two blocks is reachable ?
Thanks.
Jojo
Hi,
Thanks, i will dig it deeply :)

Hi,
From origin insn seqs, I think the insn 'r500=unspec[r100] 300’ is in
Good place because of the bypass of my pipeline description, it is not needed
to schedule.
But the result of Sched1 pass schedule it,
I check the souce code of sched-rgn.c & haifa-sched.c
From compute_priorities() I think

add supporting for these types with
computed size at runtime ?

Hi,
We know gcc supply earlyclobber function to avoid register overlap,
but it can not describe explicitly for specific source operand, is it
right ?
The vector ISA spec of risc-v describe some register overlap rules here:

Has GCC supported soft-fp for bfloat16 ?

Hi,
Are there some history or reason for this design ?
I think it’s clear & simple to keep coherent logic,
namely that there should be libgcc_eh.a for exceptions :)
Add Makefile.in segment of libgcc as following:
# Build LIB2ADDEH, LIB2ADDEHSTATIC, and LIB2ADDEHSH
