The attempt to build head -r323246 via the system clang 5 stops for the likes of:
--- agp.ko.full --- ld: agp.kld(.text+0x2e08): R_PPC_PLTREL24 reloc against local symbol agp.kld: could not read symbols: Bad value *** [agp.ko.full] Error code 1 There is a build-race and other instance of "R_PPC_PLTREL24 reloc against local symbol" sometimes occurs instead. Also not much of the kernel builds before this happens. The problem is not new with -r323246 . Back in clang 4 days I did not have this problem. I give the build details later below. There is a report of: --- ahd_pci.o --- /usr/src/sys/dev/aic7xxx/ahd_pci.c:113:10: warning: implicit conversion from 'long long' to 'bus_addr_t' (aka 'unsigned int') changes value from 549755813887 to 4294967295 [-Wconstant-conversion] ? 0x7FFFFFFFFF ~~^~~~~~~~~~~~ /usr/src/sys/dev/aic7xxx/aic_osm_lib.h:149:7: note: expanded from macro 'aic_dma_tag_create' lowaddr, highaddr, filter, filterarg, \ ^~~~~~~ before it stops. The code in question is: if (sizeof(bus_addr_t) > 4) ahd->flags |= AHD_39BIT_ADDRESSING; /* Allocate a dmatag for our SCB DMA maps */ error = aic_dma_tag_create(ahd, /*parent*/bus_get_dma_tag(dev), /*alignment*/1, /*boundary*/0, (ahd->flags & AHD_39BIT_ADDRESSING) ? 0x7FFFFFFFFF : BUS_SPACE_MAXADDR_32BIT, /*highaddr*/BUS_SPACE_MAXADDR, /*filter*/NULL, /*filterarg*/NULL, /*maxsize*/BUS_SPACE_MAXSIZE_32BIT, /*nsegments*/AHD_NSEG, /*maxsegsz*/AHD_MAXTRANSFER_SIZE, /*flags*/0, &ahd->parent_dmat); So it is actually using BUS_SPACE_MAXADDR_32BIT but it still complains about the extra bits in the other case. So (bus_addr_t) 0x7FFFFFFFFF might be appropriate to avoid such warnings. For completeness: there are also reports of . . . --- if_ale.o --- /usr/src/sys/dev/ale/if_ale.c:2115:14: warning: taking address of packed member 'rx_frames' of class or structure 'smb' may result in an unaligned pointer value [-Waddress-of-packed-member] for (reg = &sb.rx_frames, i = 0; reg <= &sb.rx_pkts_filtered; reg++) { ^~~~~~~~~~~~ /usr/src/sys/dev/ale/if_ale.c:2115:43: warning: taking address of packed member 'rx_pkts_filtered' of class or structure 'smb' may result in an unaligned pointer value [-Waddress-of-packed-member] for (reg = &sb.rx_frames, i = 0; reg <= &sb.rx_pkts_filtered; reg++) { ^~~~~~~~~~~~~~~~~~~ /usr/src/sys/dev/ale/if_ale.c:2120:14: warning: taking address of packed member 'tx_frames' of class or structure 'smb' may result in an unaligned pointer value [-Waddress-of-packed-member] for (reg = &sb.tx_frames, i = 0; reg <= &sb.tx_mcast_bytes; reg++) { ^~~~~~~~~~~~ /usr/src/sys/dev/ale/if_ale.c:2120:43: warning: taking address of packed member 'tx_mcast_bytes' of class or structure 'smb' may result in an unaligned pointer value [-Waddress-of-packed-member] for (reg = &sb.tx_frames, i = 0; reg <= &sb.tx_mcast_bytes; reg++) { ^~~~~~~~~~~~~~~~~ . . .
