| Series | [LRA] Fix PR87899: r264897 cause mis-compiled native arm-linux-gnueabihf toolchain | expand |
Hi Peter,
Thanks for the patch! It makes much more sense to me to split those functions, and use them separately.
I tried to build a native arm-linuxeabihf toolchain with the patch. But I got the following ICE:

Hi Peter, I configure and build the native toolchain with this command. By default, it will try to do a bootstrap. ../gcc/configure CFLAGS='-g -O0' CXXFLAGS='-g -O0' --target=arm-none-linux-gnueabihf --build=arm-none-linux-gnueabihf --host=arm-none-linux-gnueabihf --enable-languages=c --with-arch=armv7-a --with-fpu=neon --with-float=hard --with-mode=thumb && make -j16 | tee build.log I attached the preprocessed file. You could reproduce it with this command: /home/renlin/try-new/./gcc/xgcc -B/home/renli01/try-new/./gcc/ -B/usr/local/arm-none-linux-gnueabihf/bin/ -B/usr/local/arm-none-linux-gnueabihf/lib/ -isystem /usr/local/arm-none-linux-gnueabihf/include -isystem /usr/local/arm-none-linux-gnueabihf/sys-include -fno-checking -O2 -g -O0 -O2 -O2 -g -O0 -DIN_GCC -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -fno-inline -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector -fPIC -fno-inline -I. -I. -I../.././gcc -I../../../gcc/libgcc -I../../../gcc/libgcc/. -I../../../gcc/libgcc/../gcc -I../../../gcc/libgcc/../include -DHAVE_CC_TLS -o _gcov_merge_single.o -MT _gcov_merge_single.o -MD -MP -MF _gcov_merge_single.dep -DL_gcov_merge_single -c libgcov-merge.i Thanks!

Hi Peter, I could verify that, your patch fixes all the ICEs I saw with arm-linux-gnueabihf toolchain! There are some differences on the test results, because I compare the latest results with something which is old. I haven't test it on bare-metal toolchain yet. But will do to ensure all related issues are fixed. Thanks for fixing it!

But will do to ensure all related issues are fixed. Hi Renlin, That's excellent news! My guess on the testsuite results changes is that they're probably caused by the combine changes/fixes that went in around the same time as my patches. If you want to disable the special copy handling, which should only help things since it gives RA more freedom, you can apply the patch I mentioned here: https://gcc.gnu.org/ml/gcc-patches/2018-11/msg00379.html which allows you to turn on and off the optimization with an option. Jeff and Vlad, I think with the above results, I think the patch is ready for review. I'm attaching the latest updated patch below. Again, this passed bootstrap and regtesting on powerpc64le-linux with no regressions. Ok for mainline?

Renlin, Jeff and Vlad: requests and questions for you below... PR87899 shows another latent LRA bug exposed by my r264897 commit. In the bugzilla report, we have the following rtl in LRA: (insn 1 (set (reg:SI 1 r1) (reg/f:SI 2040))) ... (insn 2 (set (mem/f/c:SI (pre_modify:SI (reg:SI 1 r1) (plus:SI (reg:SI 1 r1) (const_int 12)))) (reg:SI 1048)) (expr_list:REG_INC (reg:SI 1 r1))) ... <another use of pseudo 2040> My earlier patch now sees the reg copy in insn "1" and correctly skips adding a conflict between r1 and r2040 due to the copy. However, insn "2" updates r1 and r2040 is live across that update and so we should create a conflict between them, but we currently do not and that leads to us assigning r1 to one of r2040's reload pseudos which gets clobbered by the r1 update in insn "2". The reason a conflict was never added between r1 and r2040 is that LRA skips INOUT operands when computing conflicts and so misses the definition of r1 in insn "2" and so never adds conflicts for it. The reason the code skips the INOUT operands is that LRA doesn't want to create new program points for INOUT operands, since unnecessary program points can slow down remove_some_program_points_and_update_live_ranges. This was all fine before when we had conservative conflict info, but now we cannot ignore INOUT operands. The heart of the problem is that the {make,mark}_*_{live,dead} routines update the liveness, conflict and program point information for operands. My solution to the problem was to pull out the updating of the program point info from {make,mark}_*_{live,dead} and have them only update liveness and conflict information. I then created a separate function that is used for updating an operand's program points. This allowed me to modify the insn operand scanning to handle all operand types (IN, OUT and INOUT) and always call the {make,mark}_*_{live,dead} functions for all operand types, while only calling the new program point update function for IN and OUT operands. This change then allowed me to remove the hacky handling of conflicts for reg copies and instead use the more common method of removing the src reg of a copy from the live set before handling the copy's definition, thereby skipping the unwanted conflict. Bonus! :-) This passes bootstrap and regtesting on powerpc64le-linux with no regressions. Renlin, can you please verify that this patch fixes the issue you ran into? Jeff, could you please throw this on your test builders to see whether it exposes any problems with the patch I didn't see? Otherwise, Vlad and Jeff, what do you think of this solution? I'll note that I have compiled quite a few largish test cases and so far I am seeing the same exact program points being used in the LRA rtl dump before and after my patch. I'm continuing to do that with more tests to make sure I have everything working correctly. I'll also note I took the opportunity to convert lra-lives.c over to using the HARD_REGISTER_P and HARD_REGISTER_NUM_P convenience macros.
